Get one or two 8800GT's, not the now vastly overpriced 8800GTX. (I recommend Evga)
Cooler master PSU's are bad. Try a Corsair, Seasonic, or Power PC and C ( I recommend Seasonic out of these). Get a Q6600 and overclock with your cooler. You could spend slightly less on a case than $170. Raptors aren't worth it anymore. Raid two larger drives in striping and acheive the same affect with more capacity.
I would also suggest getting one or two 8800gts. A single 8800gt performs very close to the gtx but for a lot less money. Also, I would suggest 4 gigs of ram, especially if you are going to run a 64 bit operating system, its very cheap right now, you can get two 2 gig dimms for relatively cheap.
