Western Digital Raptor 36GB 10000rpm SATA $188.04 x2
If anything, get two of these types of HD's but go for the 74gig versions[/b]
GeForce 7800 GTX 512MB PCI Express 3 $1399.16 x2
SLI isn't worth it at all at the time, and either is the GTX 512. Go with a higher end and factory OC'd GTX 256, and OC it from there. You won't be dissapointed.
2GB ECC PC3200 DDR400 SDRAM $420.39 x6
Go with 2 pairs of 2x512 OCZ Gold memory, it's OCable and just great memory. Like other have said, 4 gigs is insanely overkilled, even anything larger than 2gigs is considered overkill by most.
AMD Opteron 280 $2335.16 x2
Huh? Two CPU's? That's totally a waste. Anyway, go with the AMD Opteron 180 Denmark, and OC it to 2.8 or 3.0ghz, no need for all that power you want.
Creative Sound Blaster X-Fi Elite Pro $740.65 x1
Not necessary unless you are a DJ or you will be working with sound files often
Creative GigaWorks S750 THX 7.1 Speakers $859.50 x1
Same as above ...
Tyan Thunder K8WE Dual Opteron SLI $673.88 x1
Not even needed. Go with a Solid DFI mobo that supports PCI-e and Socket 939, DFI rocks when it comes to OCing.
Philips 22" 202P flat monitor $934.88 x1
I personally like LG, but this is all of prefrence and past experiences
Samsung TS-H552 Dual Layer 16X DVD Writer $63.77 x1
Sure, might as well get two of these
Thermaltake Armour Case with 430W PSU $392.63 x1
Okay case, but don't buy one with an integrated PSU. You can buy far higher end cases with more fans and more efficient cooling without PSU's
Logitech G15 Gaming Keyboard $104.61 x1
Okay ...
Logitech G5 Laser Mouse $104.61 x1
If you've got the cash sure
Enermax 600 690 Watt PSU ATX $240.00 x1
No way, I wouldn't trust Enermax ever. Go with the Powerstream OCZ 600w PSU, very solid and powerful
Windows XP PRO oem 64 bit edition $260.00 x1
OEM is that expensive? Wow, well anyway if you think your going to be taking advantage of 64 bit's minor advantages, sure why not.
