I have an old Dell V350 that I picked up from work when we got new machines. I stuck a 1.4 Powerleap CPU upgrade in it, upped the RAM to 384MB and installed a 3dfx Voodoo5 PCI card that I had. I then installed Win 98 SE and patched it with the Unoffical Windows 98 SE Service Pack. It runs very nicely. I have a few Glide games installed on it (Diablo II in particularly) and its great for them. Its not my main PC of course, but it still works fine and I don't see getting rid of it ever.
