Hey guys. I'm looking at upgrading my imac's hard drive so i can fit XP and games and stuff on there. I'm looking at the cheap Western Digital 500gb greenpower hdd. I have a few questions first. 1. how do i transfer all the data including apps, docs, settings and stuff without an external hdd? 2. Can i use a sata hdd with the core duo imac or does it need to be IDE? 3. anybody got a guide or something to help me (i'm going to clean out the dust and crap with some compressed air as well as upgrading the hdd.) thanks in advance.
