A desktop with an Intel Pentium 4 1.6 GHz CPU, 512 MB of RAM, 40GB hard drive, and older Nvidia Graphics Card. It uses Windows XP Pro.
I think it can play old games like Warcraft 3, Age of Empires, and other games made in the early 2000s.
I wouldn't consider myself a collector of old computers since I don't go on eBay to bid on old computers, or go to pawn shops to buy old computer. I just don't throw them away since I might someday need the parts like hard drive to put onto my new computers if I am running low on hard drive space, or install Ubuntu Linux onto them to use as extra computers.
