BitFenix Portal Review: A Compact Aluminum Mini ITX Case

Manufacturer: BitFenix

Introduction and First Impressions

The Portal isn't a new case by any means, but it's still a unique mini-ITX offering from BitFenix that blends an unusual design with an easy build process thanks to a sliding "dual-frame" design for unfettered component access. It offers a compact footprint while still supporting a full-length graphics card, and the aluminum exterior provides light weight and a high-end appearance.

The Portal doesn't look like your typical mini-tower mITX case, but there is just enough room for a full system inside.

On the right side we find the USB 3.0 and 3.5 mm ports, and there is some ventilation from the narrow grills on the upper right and left. The left side has the same narrow vents on the upper half.

The top of our review unit has the optional GPU window, which occupies most of the top of the case:

Down on the bottom of the case we see the most significant ventilation on the Portal:

The back of the case shows the inverted motherboard layout, with the GPU mounted above the I/O panel.

Someone really must have a sense of humor. "Compact" Mini-ITX case, hehe... The size of the thing (~29 liters without stand) would be compact if that thing were an mATX case. On the other hand, perhaps my English language comprehension is lacking and "compact" really just means nothing else than "biggish". Guess i need to check the dictionary... ;-)

Yeah, I like the look but for a mini-itx case it is huge. Each to their own obviously, but if you are going to pay the mini-itx premium, it doesn't make sense to end up with a mATX size system.

A good looking computer case for people who don't care about computers.

The Portal looks really cool and is aptly named. If it can bring down the temp a bit more, I don't mind housing my next build with it. I still might. Keeping it on my short list.

Thanks for the review.
