When I was younger - and before I had a solid non-Mac box at home - I used to collect the old PCs and miscellaneous hardware that I found discarded in my neighbourhood and salvage them into workable rigs.

I successfully installed OpenBSD on one of them, Arch on another. I actually ran a nulled vBulletin forum for my mate on one from my home internet connection for a few weeks, before he bought hosting.

I had such a great pile of shitty old 80MB IDE rives, it was insane. No pictures though, unfortunately!
