If I can find one flaw with the U2-UFO (at least with the standard back), it's that the power supply has no additional support beyond the back panel itself, and sags a little bit. But if you just put something (I used three MM case feet taped together) between the bottom of the power supply and the top of the motherboard tray, to serve as a support point, problem gone.
