Good news! I just saved a ton of money by switching to Geico, so I'm going to buy a new mac pro but I have some questions about reselling my G5 tower. How do I go about cleansing the hard drives of all my user preferences, created files, downloads etc. without WIPING the HD clean with a fresh install of leopard? I want the next owner to be able to use all the apps I have installed but none of my other crap. I really don't want to have to wipe/re-install EVERY bit of software I have on here.
