Okay, so this is what I decided, will this all fit in the case? And is the PSU good enough?
Samsung SH-S203B Black SATA DVD+RW
Coolermaster CAC-T05 Centurion 5 Aluminum ATX Tower Case
Seagate Barracuda 7200.10 320GB SATA2 3GB/S 7200RPM
Patriot Extreme Performance 2GB 2X1GB PC2-6400 DDR2 Dual Channel
Intel Core 2 Duo E6750 Dual Core LGA775 2.66GHZ
FSP Fortron AX500-A Blue Storm II 500W
GEFORCE 8800GTS 500MHZ 320MB 1.6GHZ
ASUS P5B ATX LGA775 DDR2 SATA2
Is that good enough? Still budgeting and stuff. Thanks!
