I just completed this custom build for a client. It was meant to be a good general use PC that could also be used for some gaming.
Case: Lian Li Lanbox
PSU: Antec earthwatts EA500 500W
Mobo: ASUS M4A78T-E AM3 DDR3 AMD 790GX ATX AMD Motherboard
CPU: AMD Phenom II X3 710 2.6GHz Socket AM3 95W Triple-Core Processor
Ram: 8 GB Ram (4 x 2GB) DDR3 1066
GPU: BIOSTAR Radeon HD 4650 512MB 128-bit GDDR3 PCI Express 2.0
Harddrive: 640 Gig Western Digital Sata 3.0 7200 RPM
Optical Drive: 20X DVD Burner

Quick Review: Overall this was an excellent build. Not to expensive, but still using all quality parts. Performance was very good in general use, gaming was moderately strong. But, that was expected with the budget video card used.
