Splurge a little more than 500, and you could get a very nice gaming rig capable of playing the newest games at nearly the highest settings.
Case:

This particular case has a lot of features that would cost much more with other companies, but its not some sort of shoddy imitation.

These guys have very good things to say about it
Also, note that it comes in serveral colors. I just had the link to the green one handy(it may also be the cheapest one; the colors of that line are priced differently for some reason).
Motherboard:

Its got a ton of stuff integrated, so you wont have to worry about sound cards, ethernet cards, or even firewire. Socket 939, and 4 ram slots. Quite adequately future proofed. Hell, its even got RAID.
for the cpu:
http://www.newegg.com/app/view...=19-103-499&depa=0
AMD Athlon 64 3000+ 1.8GHz, 512KB L2 Cache 939-Pin 64-bit Processor - OEM
AMD 64 bit processors are the CPUs to be buying right now. This one easily overclocked to match the power of the next model up, or even more if you want to get into overclocking.

ZALMAN CNPS7000B-AlCu Aluminum + Copper CPU Cooler
A CPU cooler. Very good one. Perfect for overclocking
Ram:

Good ram, Mushkin. Two sticks for dual channel.
Hard drive:
http://www.newegg.com/app/View...=22-148-019&depa=0
SATA and an 8mb buffer for speed. Seagate is very reputable. Even has a 5 year warrenty.
DVD burner:
http://www.newegg.com/app/view...=27-152-035&depa=0
NEC 16X Double Layer DVD±RW Drive, Black, Model ND-3520A BK, OEM
Best value DVD burner you can get. Has all the speed and features of the pricier burners, but its very affordable. I just got the 3500A (they just replaced that with this one), and I love it.
Video card:
http://www.newegg.com/app/view...=14-130-220&depa=0
EVGA nVIDIA GeForce 6600GT Video Card, 128MB GDDR3, 128-Bit, DVI/TV-Out, AGP 8X
The 6600 GT is the midrange card to buy these days. You'll be able to run all the latest games on nearly the highest settings. EVGA is just one of many brands that make it, but its competitively priced, and its available right now.

$500 is still too low for a decent gaming rig. But $800 is enough.
A few years ago, you couldn't get a gaming machine for under $1500. So, at least there's progress.
