I just built a new system myself. Here is everything I bought:
Hard Drive Western Digital Raptor X WD1500AHFD 150GB 10,000 RPM Serial ATA150 Hard Drive
Operating System Microsoft Windows Vista 32-Bit Ultimate for System Builders Single Pack DVD
Fan/Heatsink ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler
Memory G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory x2
Case Thermaltake Armor Series VA8000BWS Black Aluminum / Steel ATX Full Tower Computer Case
Motherboard EVGA 132-CK-NF78-A1 GF780i SLI, ATX, Intel 775, 3 x PCIE 16x, Dual GB Lan MOBO
Processor INTEL core 2 quad q6600 (BX80562Q6600) 2.4ghz em64t quad core w/8mb cache 1066mhz lga775-pin
Video Card EVGA 512-P3-N801-AR e-GeForce 8800GT 512MB DDR3
What I already had already had:
Power Supply BFG Tech BFGR650PSU ATX 12v 2.0 / EPS 12V 650Watts Power Supply

I built the same PC on ibuypower.com and cyberpowerpc.com to compare. I ended up saving about $300-$400 by building it myself. I have a buddy that bought from ibuypower and he is very happy. I think they're a good company.
