I think he missplaced a decimal there!

What I'm I looking at? I know it's a computer tower but whats all that stuff inside?

500 for an old 8086 PC. No wonder there are no bids. You'd have to be a hardcore collector to drop that much.
And it's not a PS2. The PS2 (featuring Microchannel Architecture!) never came in an 8086. The Model 25 was a 286.
