Need some recommendations.

Basically, all I need is something cheap that can replace my HP Compaq 6720s, it needs to run GMod and Minecraft at 30fps or above, and not have the display drivers crash from the effects of a shotgun blast at close range that uses the Realistic CSS weapon base. Trust me, it's happened before. Also, I need 3 or more USB slots, and possibly an eSata slot.

bacon soup with extra lettuce?

i'd say just go get a cheap HP desktop and put additions into it, that or build it yourself.

iBuyPower.com is a good place to find relatively cheap, relatively medium-high power computers.
