New Components, New Approach


After 20 or so enclosure reviews over the past year and a half and some pretty inconsistent test hardware along the way, I decided to adopt a standardized test bench for all reviews going forward. Makes sense, right? Turns out choosing the best components for a cases and cooling test system was a lot more difficult than I expected going in, as special consideration had to be made for everything from form-factor to noise and heat levels.

Along with the new components I will also be changing the approach to future reviews by expanding the scope of CPU cooler testing. After some debate as to the type of CPU cooler to employ I decided that a better test of an enclosure would be to use both closed-loop liquid and air cooling for every review, and provide thermal and noise results for each. For CPU cooler reviews themselves I'll be adding a "real-world" load result to the charts to offer a more realistic scenario, running a standard desktop application (in this case a video encoder) in addition to the torture-test result using Prime95.

But what about this new build? It isn't completely done but here's a quick look at the components I ended up with so far along with the rationale for each selection.

CPU – Intel Core i5-6600K ($249,


The introduction of Intel’s 6th generation Skylake processors provided the excuse opportunity for an upgrade after using an AMD FX-6300 system for the last couple of enclosure reviews, and after toying with the idea of the new i7-6700K, and immediately realizing this was likely overkill and (more importantly) completely unavailable for purchase at the time, I went with the more "reasonable" option with the i5. There has long been a debate as to the need for hyper-threading for gaming (though this may be changing with the introduction of DX12) but in any case this is still a very powerful processor and when stressed should produce a challenging enough thermal load to adequately test both CPU coolers and enclosures going forward.

GPU – XFX Double Dissipation Radeon R9 290X ($347,


This was by far the most difficult selection. I don’t think of my own use when choosing a card for a test system like this, as it must meet a set of criteria to be a good fit for enclosure benchmarks. If I choose a card that runs very cool and with minimal noise, GPU benchmarks will be far less significant as the card won’t adequately challenge the design and thermal characteristics of the enclosure. There are certainly options that run at greater temperatures and higher noise (a reference R9 290X for example), but I didn’t want a blower-style cooler with the GPU. Why? More and more GPUs are released with some sort of large multi-fan design rather than a blower, and for enclosure testing I want to know how the case handles the extra warm air.

Noise was an important consideration, as levels from an enclosure of course vary based on the installed components. With noise measurements a GPU cooler that has very low output at idle (or zero, as some recent cooler designs permit) will allow system idle levels to fall more on case fans and airflow than a GPU that might drown them out. (This would also allow a better benchmark of CPU cooler noise - particularly with self-contained liquid coolers and audible pump noise.) And while I wanted very quiet performance at idle, at load there must be sufficient noise to measure the performance of the enclosure in this regard, though of course nothing will truly tax a design quite like a loud blower. I hope I've found a good balance here.

Introduction and Technical Specifications


Water cooling has become very popular over the last few years with the rise in use of the all-in-one (AIO) coolers. Those type of coolers combine a single or dual-fan radiator with a combination CPU block / pump unit, pre-filled from the factory and maintenance free. They are a good cooling alternative to an air-based CPU cooler, but are limited in their expandability potential. That is where the DIY water cooling components come into place. DIY water cooling components allow you to build a customized cooling loop for cooling everything from the CPU to the chipset and GPUs (and more). However, DIY loops are much more maintenance intensive than the AIO coolers because of the need to flush and refill the loops periodically to maintain performance and component health.

With the increased popularity in liquid cooling type CPU coolers and the renewed interest and availability of enthusiast-friendly parts with the introduction of the Intel Z97, X99, and Z170 parts, it was past time to measure how well different CPU water blocks performed on an Intel X99 board paired up with an Intel LGA2011-v3 5960X processor. The five water blocks compared include the following:

  • Koolance CPU-360 water block
  • Koolance CPU-380I water block
  • Swiftech Apogee HD water block
  • Swiftech Apogee XL water block
  • XSPC Raystorm water block

Introduction and First Impressions

The Enthoo Pro M is the new mid-tower version of the Enthoo Pro, previously a full-tower ATX enclosure from the PC cooler and enclosure maker. This new enclosure adds another option to the $79 case market, which already has a number of solid options. Let's see how it stacks up!


I was very impressed by the Phanteks Enthoo EVOLV ATX enclosure, which received our Editor’s Choice award when reviewed earlier this year. The enclosure was very solidly made and had a number of excellent features, and even with a primarily aluminum construction and premium design it can be found for $119, rather unheard-of for this combination in the enclosure market. So what changes from that design might be expect to see with the $79 Enthoo Pro M?

The Pro M is a very businesslike design, constructed of steel and plastic, and with a very understated appearance. Not exactly “boring”, as it does have some personality beyond the typical rectangular box, with a brushed finish to the front panel which also features a vented front fan opening, and a side panel window to show off your build. But I think the real story here is the intelligent internal design, which is nearly identical to that of the EVOLV ATX.

Manufacturer: Antec

Introduction and First Impressions

The Antec Signature Series S10 is the company's new flagship enclosure, and it looks every bit the part. A massive full-tower design with seemingly no expense spared in its design and construction, the S10 boasts many interesting design details. So is it worth the staggering $499 price tag? (Update: A day after our review was published Newegg cut the $499 MSRP by $150, taking the S10 down to $299 after a $50 rebate.) 


The Signature S10 is an interesting product to be sure. Antec, long renowned as a maker of premium cases has in recent years lost some of the cachet that they once had with enthusiasts. This is no reflection on Antec and more a result of the industy's flood of enclosures into the market, with virtually every brand filling all price segments. Corsair, SilverStone, Fractal Design, Lian Li, Cooler Master, In Win, NZXT, BitFenix, Phanteks, and the list goes on and on...

So where does the new S10 enclosure fit into this market? Antec made the daring move of placing the Signature enclosure directly at the top with a shocking $499 retail price - which subsequently dropped to $449 and then again to $349 before a $50 rebate. I can think of no other recent enclosure this expensive at launch other than the In Win S-Frame, and it positioned the S10 as an unattainable object for most builders. So was Antec successful in creating an aspirational product - even before the recent price cuts?


Is that... Batman??

Introduction and Technical Specifications


The measure of a true modder is not in how powerful he can make his system by throwing money at it, but in how well he can innovate to make his components run better with what he or she has on hand. Some make artistic statements with their truly awe-inspiring cases, while others take the dremel and clamps to their beloved video cards in an attempt to eek out that last bit of performance. This article serves the later of the two. Don't get me wrong, the card will look nice once we're done with it, but the point here is to re-use components on hand where possible to minimize the cost while maximizing the performance (and sound) benefits.

We started with an EVGA GTX 970 SC card with 4GB ram and bundled with the new revision of EVGA's ACX cooler, ACX 2.0. This card is well built with a slight factory overclock out of the box. The ACX 2.0 cooler is a redesigned version of the initial version of the cooler included with the card, offering better cooling potential with fan's not activated for active cooling until the GPU block temperature breeches 60C.

For water cooling the EVGA GTX 970 SC GPU, we decided to use the WATERCOOL HeatKiller GPU-X3 Core water block. This block features a POM-based body with a copper core for superior heat transfer from the GPU to the liquid medium. The HeatKiller GPU-X3 Core block is a GPU-only cooler, meaning that the memory and integrated VRM circuitry will not be actively cooled by the block. The decision to use a GPU only block rather than a full cover block was two fold - availability and cost. I had a few of these on hand, making of an easy decision cost-wise.

Manufacturer: Phanteks

Introduction and First Impressions

Phanteks has expanded their Enthoo enclosure lineup with a new ATX version of the popular EVOLV case, and it offers a striking design and some unique features to help it stand out in the mid-tower market.



Phanteks first came to my attention with their large double tower cooler PH-TC14, which competes directly with the Noctua NH-D14 in the CPU air-cooling market. But like a lot of other cooling companies (Cooler Master, Corsair, etc.) Phanteks also offers a full lineup of enclosures as well. Of these the Enthoo EVOLV, which until today has only been available in a micro-ATX and mini-ITX version, has been well-received and has a angular, minimalist look that I like quite a bit. Enter the EVOLV ATX.

With the larger size to this new EVOLV ATX there is not only room for a full-size motherboard, but much more room for components and cooling as well. The internal layout is very similar to the recently reviewed Fractal Design Define S enclosure, with no storage (5.25” or 3.5”) inside the front of the case, which gives the EVOLV ATX a totally open layout. The front is solid metal (though well vented) so we’ll see how this affects cooling, and it will be interesting to see how Phanteks has approached internal storage with the design as well. Let’s get started!

Introduction and First Impressions

Supermicro recently entered the consumer space with a new line of enthusiast motherboards and today we’re looking at a gaming enclosure from the well-known enterprise manufacturer.


While many component manufacturers have diversified their product offerings to include everything from cooling fans to thumb drives, Supermicro is not a name that anyone familiar with the company would have likely suspected of this trend. With recent Z97 and X99 motherboard offerings Supermicro has made an effort to enter the enthusiast market with boards that don’t exactly look like gaming products, but this is to be expected from a company that specializes in the enterprise market.

It was something of a surprise to hear that Supermicro had created a new enclosure for the consumer segment, and even more so to hear that it was to be a gaming enclosure. And while the term “gaming” gets thrown around quite a bit the new enclosure does have the look we tend to associate with the moniker, with flashy red accents and a brushed aluminum front panel to go along with all-black steel enclosure.

Manufacturer: Fractal Design

Introduction and First Impressions

The Define S from Fractal Design is a mid-tower enclosure based on the company’s excellent Define R5, and this version has a new interior for enhanced cooling support with an innovative approach to storage.



I've mentioned before that the PC enclosure market is crowded with options at every price point, but this can actually be a good thing because of the high level of individual preference this permits. Selecting a case is a multi-faceted thing, and while they all (well, mostly) keep components safely housed, once that need has been met there's a lot more to consider. Let's face it, aesthetics are important since the enclosure is the outward-facing representation of your build (and personal style). Support for your preferred type of cooling, storage, and future expandability are high on the list when selecting a finalist as well, and then there's the thermal/noise performance element to consider. It was Fractal Design's own Define R5 (review here) which offered a balanced approach to these needs, and while not looking especially flashy with understated style and a standard ATX layout, the R5 was an exceptionally well-done effort overall. Now, months later, enter the Define S.

With the Define R5 offering a solid combination of silence, expandability, and build quality, why would Fractal Design create another very similar case right on its heels? It’s all about giving people choice, and that’s something I can certainly stand behind - even when it means further segmenting a market that seems almost impossibly crowded now. And when we dive deeper into the Define S we see what is essentially a companion to the Define R5, and not a replacement. At first glance this might appear to be an identical case, but the interior layout clearly separates the two. In summary, the Define S loses 5.25” storage support found in the R5, and while that previous model had no less than 8 hard drive trays the S employs a novel approach to HDD support, but cuts the drive support from 8 standard 3.5" drives to just 3 in the process.

Manufacturer: Corsair

Introduction and First Impressions

Corsair's venerable single and double-width liquid CPU coolers based on 120mm fans have been refreshed with added style and a new underlying design. How do they perform? We're about to find out!



There isn't much left to say about all-in-one (AIO) liquid CPU coolers these days, other than they are often better performing and more expensive than traditional air coolers. A good design gives an AIO liquid cooler a distinct advantage with overclocking headroom, and often in noise output as well (at higher levels of performance). This is not to dismiss air cooling as massive dual-tower coolers from Noctua and others certainly have the potential to out-perform all but the very best AIO liquid coolers, though not every enclosure will have the room for such a cooler. Thus, a good AIO liquid CPU cooler can offer not only space savings but potentially outstanding cooling performance as well. But this is a road we have traveled many times, with cost often the deciding factor even in the face of compelling evidence in favor of what are often very expensive solutions. Has that changed in 2015?

Corsair has done as much as any manufacturer to make AIO liquid CPU cooling mainstream, and their original H100 cemented the AIO's place as an enthusiast-level cooler and not simply a shortcut to traditional water cooling. The 240mm H100 and corresponding 120mm H80 have been refined a couple of times since their introduction, and though other variants such as the H105 and H75 (at the same 240/120mm sizes) have been released and crowded the market further, the H100/H80 series still occupy an important position.

Manufacturer: SilverStone

Introduction and Features



SilverStone has a long-standing reputation for providing a full line of high quality enclosures, power supplies, cooling components, and accessories for PC enthusiasts. With a continued focus on smaller physical size and support for small form-factor enthusiasts, SilverStone recently introduced the new SX500-LG. There are currently five power supplies in the SFX Series, ranging in output capacity from 300W to 600W. The SX500-LG is the first one to feature an extended chassis. The SX500-LG enclosure is 30mm (1.2”) longer than a standard SFX chassis, which allows using a quieter 120mm cooling fan rather than the typical 80mm fan used in most SFX power supplies.


150mm                                130mm                              100mm

The new SX500-LG SFX-L Series power supply was designed for small form factor cases but comes with an ATX adapter plate so it can be used in a standard ATX enclosure as well. In addition to its small size, the SX500-LG features high efficiency (80 Plus Gold certified), all modular flat ribbon-style cables, and provides up to 500W of continuous DC output. The SX500-LG PSU also operates in semi-fanless mode (cooling fan turns off at low power).

Note: We have seen rumors on the web about the new SX500-LG power supply being a re-packaged version of the SX600-G that SilverStone recalled awhile back. Rest assured it is not. The SX600-G is a completely different PSU made by Enhance and the new SX500-LG is made by High Power. And yes, the SX500-LG is officially listed as an 80 Plus Gold certified PSU (10-22-2014).

Here is what SilverStone has to say about the new SX500-LG PSU: “For small form factor enthusiasts, the standard SFX power supply form factor has an excellent combination of size, power, and affordability. At 100mm deep, however, the standard SFX PSU is also limited in fan size to 80mm. While advances in engineering and components have modern high-end SFX PSUs quieter than ever, there is still inherent limitation with 80mm fan’s ability to dissipate heat at maximum loading conditions while maintaining satisfactory noise profile for users sensitive to higher-pitch sounds. With this in mind, SilverStone has released a “lengthened” variation of the SFX form factor called, SFX-L. With 30mm of added depth, a SFX-L power supply has enough room to fit a 120mm fan, thus its maximum load noise can be not only lower in intensity (via slower fan speed), but also lower in pitch (due to larger fan size). The first model to debut in the SFX-L will be the SX500-LG, a 500W model that includes all features available from top of the line SFX SilverStone PSUs such as 80 Plus Gold efficiency, modular flexible flat cables, and semi-fanless capability. An ATX adapter bracket is included as well to enable users to install this PSU into any small or even larger cases that do not have SFX mounting holes.

SilverStone SX500-LG V1.1 SFX-L Series Power Supply Key Features:

•    New SFX-L form factor (and ATX via included adapter)
•    Silent running 120mm fan with intelligent semi-fanless operation
•    500W Continuous DC output (up to 40°C)
•    High efficiency with 80 Plus Gold certification
•    100% Modular cables, flat ribbon-style
•    Strict ±3% voltage regulation with low AC ripple and noise
•    All Japanese made capacitors for reliable operation
•    Powerful single +12V rail with 40A (480W)
•    Two PCI-E 6+2 pin connectors
•    Protections: UVP, OVP, OPP, and SCP
•    Universal AC input and Active PFC
•    MSRP $99.99 USD

Introduction and First Impressions

SilverStone has another contender for a budget ATX build with the Kublai KL05 enclosure, and today we’ll take a look at the windowed variant of this mid-tower design.


What would life be like without computer cases? Various components strewn about on desks, tables, and floors, creating headaches and tripping hazards everywhere. Fortunately, they exist, and I'm thankful for this every day. However there are now so many that scrolling down the list on any site in any price range is like shopping for RAM or power supplies these days: endless selection of similar things. But it's not enough to make sure the specs match your build as enclosures can vary a great deal even with the same component support. So, when looking for a good case for a build or upgrade you just end up reading a review like this. I hope I don't disappoint you, and we have a pretty interesting offering from SilverStone here to consider.

I've been enamored of late with lower-priced components. Sure, I've reviewed $300 cases but as cool as the high end can be it's not realistic for a lot of people (myself included). Finding great value has always been kind of fun, and to me a great value for a PC enclosure is something well under the $100 mark. I had the pleasure of reviewing NZXT's excellent S340 enclosure recently, and the SilverStone Kublai we're about to take a look at carries the same $69.99 MSRP. A larger case than the NZXT, the Kublai retains support for 5.25" optical drives and makes use of this added space up front for plenty of hard drives. The case looks and it sounds like a good value, but there's only one way to find out (and it involved actually reviewing it).

Noctua is a well known player in the enthusiast market for highly efficient, low-noise CPU cooling solutions. The latest additions to their lineup, the NH-D9L and NH-U9S, are smaller than the typical coolers we've reviewed here at PC Perspective in recent times. However, Noctua again proves their design prowess with the fact that these coolers held up to the rigorous demands of our testing at both stock and overclocking settings. And we all know that the Haswell and Haswell-E processors put major pressure on the cooling solution as the core speed and voltage is increased. Both coolers come standard with Noctua's SecuFirm2™ mounting mechanism, ensuring a secure mount between the cooler and CPU.

The NH-D9L CPU cooler is a dual tower cooler with a single included fan sandwiched between the two cooling towers. The unit can support up to three fans if desired. Noctua designed the cooler with their typical hybrid approach, combining a copper base plate and heat pipes with aluminum finned cooling towers. The base plate and heat pipes are nickel-plated for looks and to prevent corrosion. At an MSRP of $59.90, the Noctua NH-D9L offers puts a premium cooler within reach of the majority of computer enthusiasts.

The NH-U9S CPU cooler is single tower cooler with a single included fan, whose radiator is about double the thickness of a standard 25mm fan. The unit offers support for up to two fans if desired. Like the NH-D9L, the NH-U9S combines a copper base plate and heat pipes with aluminum finned cooling towers for an optimal hybrid cooling solution. The base plate and heat pipes are nickel-plated for looks and to prevent corrosion. The NH-U9S also retails at an MSRP of $59.90, giving potential users another affordable choice for cooling their processor.

Manufacturer: NZXT

Introduction and First Impressions

NZXT has created a stylish mid-tower enclosure with their Source 340 chassis, and made it an especially attractive option with a retail of just $69.99. Can this new case contend in a crowded market? We will find that out here!


With several interesting designs under their belt NZXT isn’t a surprising name when it comes to nice-looking enclosures. I looked at their H440 Razer Edition recently, and the H440 it was based on is a popular mid-tower enclosure with good looks and performance. This new S340 is very similar to the H440 but on a slightly reduced scale, and offers a more open internal layout with a reduction in hard drive storage space. This is a move that won’t work for everyone, but as I mentioned in the recent SilverStone Raven RV05 review being limited to a pair of hard drives and SSDs a fair tradeoff for a gaming or productivity setup.

On the subject of storage, like the aforementioned H440 and RV05 this Source 340 enclosure is another example of a optical bay-free design. There are no hidden slim-ODD bays here, and for any optical data needs a user will be required to use an external solution. I personally like an open layout and don’t use 5.25” bays at all anymore, and the added room in the S340 provides nearly unlimited space for long GPUs and stays clean with a clever approach to cable routing.

Features and Specifications

If you are looking for the biggest, baddest, power supply on the planet, then we have an exclusive review for you today.  But you better have a truck, a couple of strong friends, and very deep pockets!  


Miller Electric has been manufacturing large, industrial-grade power supplies since 1929.  They are one of the few power supply manufactures who actually design and build their own products, right here in the USA.  Miller’s The Power of Blue series of high-capacity power supplies includes models that go all the way up to an astounding 10,500 watts!

While we were not able to obtain a review sample of Miller’s flagship 10.5kW unit, we do have an exclusive review of the Miller XMT 300 PC, which can deliver up to 4,500 watts of pure DC power.   Talk about having some extra reserve capacity… wow!


The Miller XMT 300 PC is an external power supply that is about twice the size of a typical mid-tower case and is designed to normally sit on the floor.  It features a unique single, high-capacity +12V rail capable of delivering up to 375A (4,500W).  A power distribution module mounts inside the PC where the normal ATX power supply would go and breaks down the incoming +12V to the minor rails +3.3V, +5V, etc., along with providing a standard set of cables and connectors.  This allows one XMT 300 PC to power multiple PCs at the same time; up to twenty computers.

Miller XMT 300 PC Key Features:

•    Monstrous, single rail +12V output (up to 375A peak)
•    External main power unit sits on the floor
