Ok since you are the experts ill put down what i already ordered maybe you guys can tell me if i did ok, andi still need a couple parts, so with this stuff in mind maybe you can help me pick the Power Supply and Case

here goes

eVGA 256-P2-N518 Geforce 7800GT 256MB 256-bit GDDR3 VIVO PCI Express x16 Video Card

eVGA 133-K8-NF41 Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard

AMD Athlon 64 3700+ San Diego 1GHz FSB 1MB L2 Cache Socket 939 Processor

CORSAIR XMS 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel Kit System Memory

thats what i got, still need power supply and case
Lookin to stay relatively cheap, so keep that in mind,
Hows the stuff i got?
Whats a good Power Supply for the money?
And when it comes to case, i like futuristic lookin but still good, for example i like the NZXT stuff, but if there is other better stuff for same or better price any info would be cool.

Thanks in advance this Forum is the best

fsp 500 watt psu

centurions are good cheap cases, heres the list of them

If you wanna overclock, get an opteron and crucial ballistix or G.SKILL instead of xms. If you don't want to overclock, go for value RAM cause the XMS stuff isn't really worth the extra money. sorry didn't realize you already had the stuff you mentioned

Previous poster nailed it. Just be sure not to get a MicroATX case out of the list posted.

Since your a first time builder, you might want to have a guide nearby for quick reference. I recommend this one.

Antec SmartPower 2.0 SP-500 ATX12V 500W Power Supply

This PSU is fine but just to be on the safe side - I don't believe it to be enough to be honest. You have quite a powerful PC. It's going to need a lot of juice. While the Smart Power is good, it won't have those steady 3% clean regulation that the TruPower has. Either way, as long as you don't overclock or push anything, the SmartPower will be fine.
