I've finally settled on the Asus A7V board, but it doesn't have any ISA slots, so I'm gonna have to replace my modem and soundcard. I'm also going to have to get a new case if I want to keep everything cool, 'cause my current case only has one fan in front, and I'd rather have one in front and at least one in back. I'll probably end up spending about $600 on the new system, but that will leave me with enough old components for my old computer to run also. The only other things I'll need for the old system are a network card and a video card, which I oughta be able to buy used fairly cheap.
