Newbie here so be gentle! I'm a windows and occasional Vista user but want to be introduced to the world of the mac! I want to know that i'll get along with it so don't wanna spend too much so i have two options 1. Get an old G4 powermac 2. Buy a couple of damaged iMacs and build them up I have quite a lot of experience building windows PCs but know NOTHING about Macs! How difficult would it be to but an iMac with a damaged screen but ok board etc and buy one with a screen that worked and combine them to make a working machine? ANY help is very much appreciated!
