My attempt at a budget PC... ur thoughts?

This rig will be running WinXP SP2 and will be replacing the 5 year old community PC in my household.

CASE - Apevia X-Cruiser

HDD - Barracuda 320GB

RAM - Corsair XMS2 (2 x 1GB)

PSU - Cooler Master eXtreme 500W

Sound - Sound Blaster X-Fi XtremeGamer

Mobo - MSI K9AG

CPU - Athlon 64 X2 5200+

GPU - Sapphire X1950Pro

This comes out to about $620.00 after all the MIR's and shipping costs.

What do you think? Any suggestions?

For the same price, you can get a case twice better than the Apevia X-Cruiser.

You should however, change that PSU if you can. If not, its generally an okay PSU.
Pay a little more and get this if you can - http://www.newegg.com/Product/Product.aspx?Item=N82E16817139003

And finally as a personal though, throw out that X-FI soundcard. Waste of money IMO.

2 things:

1. I think the power supply will be fine for a budget-minded "community" PC.

2. A generic SB Audigy will perform just as well as an X-Fi card unless you're using some really high-end speakers.
