The case isn't that good. Get a Lian Li V1000 instead.
And what are you doing getting just one 7800GTX? Are you crazy? Get a second one for SLI.
I also don't see a PSU. How are you going to power all of that? Get a PCP&C 850, hands down.
The RAM you got ain't that good either. Get a 2x512MB Gskill PC4400LE dual channel kit. You can get better timings and it's faster (2.5-4-3-7 at 325MHz for DDR650 with just 2.9V).
Also, BTW, the 7800GTX's don't support the 30" Apple Cinima, last time I checked. It'd be better if you go the Dell 2405FPW.
