I got it, the thing is gorgeous, and dead silent. Amazingly well built.
Also the raptors are nice but I don't think the very small performance increase over the WD drives is worth the huge price/meg increase. If you get 2/750 gig drives throw them in raid 0 you should be good to go.
The main board you have is nice, but I would also recommend the P5k-Deluxe Wifi.
Forgot to add the 2 geforce cards is a waste of money. One is fine.
