Rather than spending time figuring out how to upgrade and doing it, you'd be better off spending time looking for deals and getting a new PC. I got a Compaq with Sempron 2800+, 256MB RAM, 40GB HD, 8x AGP and 5 PCI slots 4 only $170. Now tell me you can upgrade to a better PC with less money. Oh I forgot to mention, keyboard and mouse were thrown in for free.
