Glad to see you are learning so much. Obviously not an english major

j/k.
Anyways, just look for a cheapo Dell PC. You can get rid of the monitor and save some cash. If you REALLY want to build you own, here is what I would do:
CPU: s754 Sempron 2600+ ($70)
Mobo: Cheap s754 board with integrated video ($60)
RAM: 512 MB corasair value ($40)
Case/PSU: ANtec SLK1650 w/ 350W PSU ($65)
HDD: Cheapest 80GB (on sale maybe $40)
DVD: NEC 3540A ($45)
Total: $320 (plus shipping)
Not too bad... For an extra $100 or so you could get a venice 3000+ and a Radeon XPress 200 board. That will be quite a bit faster and have better integrated graphics (around an x300SE, that may be able to play some semi recent 3D games, of course at low settings), up to you...
