I picked an old PC, clearly already upgraded several times:

The case belongs to a generic 386, (with the ever-cool TURBO! button)

ASUS mobo, P1 133, 64Mb ram, no optical drive, 2 hard disks (1G & 3.5G)

A great man once said "There's no kill like overkill.""

So I added a 200MHz P1 processor, a 40GB hard disk, a 60GB hard disk, a DVD-RW drive, a Zip drive, a USB II card, and an ATI 128mb PCI video card. Also, several fans (the single fan in the PS wasn't cutting it).

It seems like a hamster driving a bulldozer, but it works well enough!
