Geeks.com has a boatload of old Apple iMacs with prices beginning at $58. The computers themselves, which range from 333MHz G3s to PowerMacs to 700MHz G3s aren't that useful as actual computers anymore, but it could be a nice addition for that nostalgic Apple fan, or they could be good for mods like an iMac ashtray or iMac fishtank.
