It's an optimized meshify c: the meshify mini². I like it a lot for being a good air cooling enclosure: 120mm exhaust, wide enough for good* tower coolers, direct air intakes, and room for oversized gpu coolers. I bet noise levels would be pretty good, too, if the side panel is well sealed. I imagine I'd end up using an itx board anyway since matx tend to be spartan on the feature set and use 120mm intakes because nothing yet rivals the a12x25 fans. I'd much rather it stay at this size and flexibility, though, than save 2-3L.
*the cryorig h7 (145mm) seems to be essentially out of stock at most US retailers. was it discontinued? the scythe fuma rev b also seems to be on the way out, with the fuma 2 having grown 5mm to 154.8mm. hopefully another product steps into that 145-150mm void, as being able to use an a12x25 on a tower cooler would be my primary draw toward this case.
