Depends on which kind you want. Get: Geil, Kingston, Crucial, or Corsair. Make sure that they're those brands or you'll suffer for it later. Which kind you need is dependant on which processor and motherboard you have. PC2100 should do the trick to be safe...unless your motherboard doesn't support it, but I imagine it does.

I've never heard of uATX, but I assume it's the same as regular ATX. I know that I own a Hewlett-Packard that came in a mini-ATX case. The power supply was 90 watts (ha ha) and the motherboard was really, really small. About 2 months ago I literally tore apart the HP case and took the motherboard completely out of it. I put it into a regular ATX case with a 350 watt power supply. It works great...and now it has plenty of room. So yes, it can work, but it might take a bit of PC knowledge and experience to get it working.

That'd be the first thing I did. I'd save up and get a motherboard that allows AGP videocards. PCI busses work, but they bottleneck the videocard badly, even when it's designed for PCI. AGP cards are so much faster than PCI cards that it would be better to simply save up and get a new mobo and videocard at the same time. You should be able to use the same processor on the new motherboard as long as you buy the compatible mobo for the CPU. A new motherboard would probably come with sound. Yes, you would need a new case. Good luck!
