The E4500 has a FSB of 800 MhZ(200 MhZ clock speed). Even if you overclock some, you'll have to run the RAM at less than DDR2 800; Maybe you could get slower RAM(PC5300, say) for less money, or spend the same money on slower RAM, but use more than 2GB of RAM since some of the memory will be used by the onboard video.

I recommend NOT getting a "lunchbox" PC case & I definitely wouldn't put a lot of faith in the Apevia 420W PSU. Get a mid tower case w/o PSU & buy a decent PSU separately.

Sabertooth, I checked that out, and I couldn't get an email that worked, all of them didn't for some reason. kx5m2g and jam, Ill take your advice and make some revisions. Biostar P4m800-m4 Pentium 4 Prescott @ 3GHz 1GB Corsair PC3200 RAM Geforce 6200 AGP 2 80Gb Harddrives XP Home SP2

Well I think that build is quite good for the budget. And I have got to know that there is a deal on the OCZ 2GB ( 2 X 1GB ) Platinum PC2-6400 DDR2 memory for $34 , I think you can get that pair.

Fry's Outpost.com has 2GB (2 x 1GB) DDR2-800 (Corsair or Crucial) for $20 after rebate.
