What are you going to use the computer for? Looks like a pretty nice build. I personally would of gone with a DFI mobo, but to each his own. Nice proc, and vid card. Glad you know what your talking about with the PSU. More than likely you'll want to upgrade it. Nothing else looks wrong with the build. Not familar with pqi brand ram, but I'm a newb, so what do I know. You'll be happy.
