Also look into getting two 74Gig Raptors instead of 1 150gig, it might be cheaper and you can setup a raid.
There's my two cents. If you decide to open a bit more money up we would love to help you with watercooling
A single 150GB raptor performs better that RAID0 74GB Raptors. Plus they cost about the same...
The memory only comes in a 2GB kit unfortionately, I would get this memory even though it it price. Best memory available, which will allow you to Overclock to your processors full potential
Other than that Snerp summed it up well... Go for a well rounded PC, FX57, 7800GT, Raptor 150GB, fast RAM, good mobo, and water cooling.
