The Cooltek UMX2 is one of those cases a user should buy if design is the most important factor. Clocking in at 170€, it is important for the user to have the ability to look past various functional issues Cooltek hazarded to preserve the chassis' overall looks. We usually do not judge the interior too harshly with such cases, but the UMX2 really pushes it with its advertised full-ATX compatibility. The chassis is essentially incapable of properly housing such a motherboard without removing the two fans in the bottom. It would have been smarter of Cooltek / Jonsbo to make this a mATX chassis, or to at least not include the two bottom fans for a lower price tag and the choice of buying fans with a smaller board instead of being left with two unused cooling units with a fully sized motherboard. Then there is the unusual placement of the motherboard-tray opening as it is essentially useless because it has been placed too far to the right for modern motherboards. Those facets taken aside, however, the UMX2 does make a rather nice impression. Sure, you will not fit a CPU cooler of more than 150 mm or an extraordinarily long PSU into the chassis, but the purpose of the chassis is to look cool, not swallow high-end gaming gear. The engineering that was put into the PSU bay and the HDD trays is refreshing, and the overall quality of the UMX2 is as you would expect of designer chassis. Even stuffing the chassis with all the hardware it can muster, the interior is surprisingly clean as all cables can be routed behind the motherboard tray. In the end, though, the UMX2 becomes a bit tough to recommend as you will not be able to use it as advertised without compromise.
