Get PCP&C Silencer 610. And consider the MSI P35 Platinum.

just my opinion but never heard anything bad about em. solid psu's and not expensive. modular cablign is handy too, especially if your going with the antec 900 case. Anything to help wire-managment is a bonus. everything else after the suggestions looks smokin ^^ will be nice system for sure.
