We never thought we’d see a sub-$100 case with tinted windows, but lo and behold, Sigma’s Unicorn has lived up to its name and shown us the impossible by “blinging up” the exterior of an otherwise stale case. Like spinning rims on a minivan, however, not all of Sigma’s design decisions are well thought out.
The front panel features one of the bulkiest doors we’ve ever seen. We guess Sigma was trying to spruce up the case’s facade with the protruding front profile, but as far as we’re concerned, it just extends the length of the chassis. And we’re miffed that the door covers the front-panel connectors entirely.
Sigma makes another questionable choice with the heavy horizontal bar running across the case interior. The bar is designed to help hold your PCI cards in place while an 8cm fan handles the cooling. But the locking mechanisms are unnecessary, and you have to remove the entire retention bar just to install or tweak parts in your rig.
The case comes with more than enough cooling and screwless installation mechanisms to make any enthusiast happy, but no support for HD audio. And while we appreciate the hidden toolbox that rests under the case’s four drive bays, it’s too little, too late given the predominance of peculiarities in this not-so-magical Unicorn.
