Consider for the case: Antec 900.
Motherboard: MSI P35 Platinum.
Memory: with the Corsair, get to 950MHz stable, you need to drop to 4-4-5-15. I dont know how well Ballistix performs so im just giving some numbers to compare with.
Raptors are a rip off.
You should wait for RV670s release in a few weeks. It would be stupid not waiting that little bit longer for a card that could offer so much more performance.
That PSU is good but you should also consider PCP&C 610 if you dont mind it being non modular.
