Looks like I have a chance of picking up a Mint! G4 iMac for fixing a Sony Vaio laptop. It is in exactly the same condition as when new (except some slight discolouration in the drive tray cover). It has the original OS, original RAM, screen is stunningly perfect. I hope she will part with it in lieu of fees, or I may even throw her a few dollars on top.
Oh, here is what it look like BTW - http://www.jeremyreimer.com/postman/files/images/imacG4.jpg
Fingers crossed! 



Truth be told it's mostly just crap Pentium 3-4 PCs, but they do get in gems from time to time (the three Power Mac G4s I got recently, for instance, and my Tandy 1000RL.) I have seen the occasional late-'80s minicomputer box in the process of being destroyed, but if I started collecting those I'd need way more space than is available in my apartment...
