$500 gaming rig?

I'm building a system for a friend who games a fair bit but needs a system for about $500. To afford a decent video card socket 745 seems to be the way to go in this price range. After some research this is what I've come up with;

BIOSTAR TForce6100 Socket 754 GeForce 6100 Micro ATX MB $69
AMD Sempron 64 3000+ Palermo Socket 754 Processor $76(when bundled with the MB)
G.SKILL 1GB DDR 400 (PC 3200) $72
eVGA Geforce 6800 256-P2-N384 Video Card $99(after rebate)
Western Digital Caviar SE 250GB 7200 RPM Serial ATA150 HD $95
IN WIN IW-Z720T.J300BFU2AD Black Steel MicroATX Mini Tower Case 300W PSU $38
NEC Black IDE/ATAPI 16X DVD±R DVD Burner $38
------------------------------------------------------------------
Total = $487(all prices from newegg, shipping not added yet)

How does all this look to you guys? Any suggestions would be appreciated.

Yeah, the motherboard was one of the things I wasn't certain about. That Biostar board got 5 stars average rating based on over 100 reviews(plus -$10 on the processor) so I figured it was a decent choice.
As for the ram, I've read that socket 754 boards don't support dual channeling so I'd rather keep a slot free for an upgrade to 2 gigs at some point. A gig of Corsair ram with the same cas latency(2.5) cost 40 bucks more so I figured I'd go with the cheapest that is well reviewed.

The Corsair ram is higher latency tho... I've read that for gaming lower cas latency can be signficant.
I've never heard of GSKILL either but it hasn't got a single bad review out of 23. Is it worth it to go with the Corsair over the lower latency stuff(plus it has a heat spreader) at a similiar price?

That all looks quite nice to me for the money spent...

With a PCI-e slot, he might be able to add a 7800GT for $250-ish a few months down the road which would double his gaming framerates....

I'd also have him add another GB of mem at the earliest opportunity..

No, not at all.. I recommand 500W PSUs to most people, but you can probably get buy with a 400W. Antec will sell you a 550W for $89 with a $15 MIR to make it $74.
