What are you looking to do with this computer?
I just threw together this SFF system:
ASUS P5E-VM HDMI mATX LGA775 G35 DDR2 PCI-E16 2PCI-E1 PCI SATA2 RAID Sound HDMI VGA Motherboard
Arctic Cooling Arctic Fan 8025L Low Speed 80MM 1500RPM 18CFM 18DBA FDB x2
Silverstone Sugo SG02B-F Black SFF mATX Case 2X5.25 2X3.5INT No PS
Intel Pentium Dual Core E2200 Dual Core Processor LGA775 2.2GHZ 800FSB 1MB Retail
Patriot Extreme Performance 4GB 2X2GB PC2-6400 DDR2-800 CL4-4-4-12 EPP Dual Channel Memory Kit
System is for general internet/office use, so no video card needed, and I stuck in an old HDD and an OCZ PSU I had lying around. System could support a quad-core, 8GB of ram and an 8800 card though.
