for your video card get an eVGA 7900gt KO
it has a copper heatsink which will keep you cool
i wouldnt go with a raptor.
instead i would get like a 250 gig hard drive 7200 rpm
i dont see raptor as well worth it right now
you may want to consider getting 2 gigs of ram as opposed to 1gig.
its really up to you but i would def. upgrade it
or maybe just purchase a 1 gig stick and later when you have the cash put in another 1 gig stick to equal out at 2 gigs
Corsair is a good choice though so stick with that bro!
everything else is great
you should have no problems
