Need suggestions for new computer I'm planning to build.

I'm planning to build a gaming PC for my little bros. They don't need anything crazy since I bought them a 360, PS3 and Wii.

Here's what I got so far:

COOLER MASTER Elite 330 RC-330-KKN1-GP Black SECC ATX Mid Tower Computer Case - Retail = $39.99
EXCELSTOR Jupiter Series ESJ9250S 250GB 7200 RPM SATA 3.0Gb/s Hard Drive - Retail = $48.99
ECS A780GM-A AM2+/AM2 AMD 780G HDMI ATX AMD Motherboard - Retail = $59.99
ASUS EAH4850/HTDI/512M Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail = $152 (After mail in rebate)
OCZ 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model OCZ2P8004GK - Retail = $49.99 (After mail in rebate)
AMD Athlon 64 X2 5400 Brisbane 2.8GHz Socket AM2 65W Dual-Core black edition Processor Model ADO5400DSWOF - Retail = $87.00
Antec BP550 Plus 550W ATX12V V2.2 SLI Ready CrossFire Ready Modular Cabling Active PFC Power Supply - Retail = $59.99
LITE-ON 20X DVD±R DVD Burner Black IDE Model DH-20A4P-04 - OEM = $22.99

In total its $613.24 but after mail in rebate its gonna be around $543.24

I'm planning to keep the Radeon HD 4850 for myself and I'm gonna give them my Geforce 8800 GT 512mb video card instead.

Em I missing something? buy an extra fan?

Most important I need help with the motherboard wasn't sure what to choose.

EDIT: Just notice that the links to newegg.com aren't working.

 

I would go to the Intel side for the CPU. They seem to be abusing the AMD chips right now. Pretty sneaky with the GPU swap!:-D
