Fractal Design has introduced the Define Nano S enclosure; a new, mini-ITX version of their popular Define S mid-tower.

The Fractal Design Define S was our pick for 2015 enclosure of the year (in our year-in-review podcast), and this new mini-ITX version retains the larger enclosure's design aesthetic - and its support for full-size components.

"The Define Nano S is an ITX case that features compatibility with high end, full-size components, superior sound dampening, and an ATX-like layout."

Key features for the Define Nano S from Fractal Design:

  • A Define Series ITX case designed for silent computing with sound dampening and ModuVent™ technology
  • User-friendly construction with superior cable management and compatibility for full-size components
  • Flexible storage options with room for up to 4 drives
  • Accommodates a variety of radiator sizes and includes brackets for reservoir and pump mounting
  • Features two Dynamic Series fans — 1 GP-12 and 1 GP-14 — with an adapter included for motherboards with limited fan headers
  • Featuring an open interior allowing an unobstructed airflow path from the front of the case to the rear exhaust
  • Easy-to-clean filters on the top and bottom, spanning the PSU position, with the bottom filter ejecting from the front for easy-access.

The Define Nano S offers a great deal of room for a mini-ITX enclosure (the Nano S is approximately 13.5 inches high, 8 inches wide, and 16.2 inches deep), with support for up to a 240/280 mm radiator on both top and front fan mounts, with 6 fan mounts overall (two of Fractal's Dynamic Series fans - 120 mm and 140 mm - are included). And an important detail; both the bottom and front fan mounts feature removable dust filters.

The enclosure offers the same "ModuVent" removable top vents, allowing more silent operation if the user doesn't need to use the upper fan mounts. There is sound dampening in place throughout, allowing for a quiet build. Storage mounts are behind the rear panel (as in the Define S) supporting two each 3.5-inch and 2.5-inch drives. GPUs up to 315 mm and CPU coolers up to 160 mm are supported along with ATX PSUs up to 160 mm deep.

Pricing will be $64.99 for the standard version, and $69.99 for the version with a window. Availability is set for March 2016.

I love the idea of an ITX case done up exactly like a short ATX case. This is the case I was hoping the 250D was going to be.

I might just have to get this case once i upgrade from Micro ATX to Mini ITX. Thought i really like my Carbide Air 240, its a bit limiting when it comes to GPU's that are too wide. Length wise its great though.

Does this put a graphics card pretty much on top of the power supply? I might be looking at it wrong, but it looks odd from an air flow point of view

you are right, and maybe that is also why they don't show a picture with a PSU.

Yesterday, when I saw Fractal Design's showcase video for the Define Nano S my first thought was this is in response to the Phanteks Enthoo Evolv ITX as direct competition. So I did a scale image comparison between the Evolv ITX and the Nano S by overlaying rear view photos of both lining up the PSU mounting screw holes. I wanted to see which case had more GPU breathing room. The Nano S has less space between a 2-slot GPU and the PSU then the Evolv ITX has. Bear in mind that the Evolv ITX has a PSU shroud in between, but it's also heavily perforated with holes. For non-reference multi-fan cooler GPUs this GPU/PSU breathing room gap may make a difference, I don't know?

You can always use an SFX power supply (e.g. silverstone) which go up to 700W, more than enough to power whatever you can cram in this case. The smaller size of the SFX psu's should allow more breathing space (they even come with ATX mounting brackets)

Also I would think a reference style cooler on the GPU that exhausts the air straight out of the back should work fine as long as your PSU isn't too long

Damn that's sexy. That may just be the 5th Fractal Design case I own.

I have also heard that Nano S Mini-ITX is better version and takes less energy and has smarter system. However when I bought my term paper I have found out about Mini-ITX a lot and now I would definitely buy it.

Is this phishing?

the post doesn't make any sense, and I don't trust the url.,II don't dare going there to test it out.

Please delete the above post. SPAM at best. Malware at worst.

how much smaller (If any) would this be than my Core 1000 from Fractal?

January 19, 2016 | 09:13 AM - Posted by Jann5s

Core 1000: Case dimensions (WxHxD): 175 x 355 x 420mm
Define S nano: Case dimensions (WxHxD): 203 x 330 x 400mm

For someone who wants a build with an 280 AIO in the front for the cpu and an other rad for the gpu on top/rear, it is perfect!
