Bought this case recently for a high performance mini ITX build. It's really well built and well ventilated although it is quite a bit larger than most other mini ITX cases (but you get the benefit of being able to use a full ATX power supply).

Just be aware that if you plan on installing the Corsair H100i GTX in this case that the fit is VERY tight and with the majority of motherboards available there is only one way to mount it which forces you to remove the front intake fan from the case to get it to fit. The fit is so tight that I just managed to get the motherboard screwed in and the mounting screws for the radiator press against the side panel (so you have to squeeze it in to get it to slide in again).

All in all though it's a really great case but I wish the H100i fit a little easier so I could keep the front fan installed.
