The other thing that bothered me about my ol' computer is that with only 1GB RAM, it starts loading stuff into swap fast. I don't know when this started, but it didn't bother me before spending a month with a laptop with 2GB. My motherboard (Tyan Tiger MPX) is supposed to support 4GB, but it turns out that it only boots with 3GB. With the fourth stick in, it gives me the beep code for VIDEO CARD ERROR. This is not the best motherboard ever made.
Still, three gigs ain't bad. Looks like I'll have to eat the NewEgg restocking fee, though.
That wasn't so cheap, but I'm considering a cheap upgrade as well. There are a bunch of Athlon XP 2400+ chips being dumped on eBay. These are the highest my board supports. It's easy to modify an XP to support SMP
by connecting one bridge with a conductive pen. Should be ~$30 for an extra 400MHz per chip. After that, I've pretty much hit the wall with this system.
