Alright, so I was going to make her a dirty Pentium 4 system, but you guys talked me out of it to say the least. So I have a case, Power supply, and all the case mods for it. Now for the actual system, lolz... I want to keep this PC as cheap as I can but still get decent hardware. All this PC will most likely be used for is facebook, net surfing, and a few papers for college. As I said, my budget is around $200, buuut, if any of you can find some good ways to budget it less, props.

Any thoughts?
