Hi all, I have finally ordered my first Mac ever (on Sep. 1 actually)! I ordered a Power Mac G5 2x2GHz rev. b (with bluetooth and a radeon 9600 xt), yeah... I will upgrade the RAM later, when I have more money So, it seams like I will get it soon because I got an email that said that it's being shipped. That's great, but now... I have one question: Is it a good idea to reformat the hdd and reinstall the OS when I get it? (I remember that I was doing that kind of stuff with my PC when I was a windows user). Or is it a "clean" install of the OS from the beginning? Thanks for your help.
