Completely disassemble it, sell all the parts seperate on ebay. Some will hate you for it, but you will make more money that way. Personally i wouldnt care if you hung it from a tree and used it for target practice, it's your stuff.
Then if you just wanted it to find a good home and didnt care about making money off it, you could always put it up for a pledge towards something, like say AROS bounty or a donation to your favorite amiga website.
