I want to know if I can put a iMac Slot Loading DVD drive in an old Power Mac, like a 7500 or a 7100, or a early G4!? I want to know this because there is one for sale on ebay, at a good price too! The URL is: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2026161816 so you guys can check it out. Please try and help me. Thanks bye!
