Unngh.
Don't even bother getting a socket 1366 chip right now. Sandy Bridge was just released and it it quite a bit faster and cheaper. The card you chose is old and pretty crappy. With the rest of that computer you should be spending about $220 or more on a card. A 1000w PSU is also not very practical. That computer wouldn't consume more than 600w. Shoot for about $80 and an 800w.
I can't contemplate why everyone thinks they need a 1tb harddrive. Are you really going to use that much? Most people never go over 500gb even with an assload of games.
I would also go with a different case. It doesn't really matter though. The HAF 922, CM 692 and Antec 900 would all probably be better.
