Hi guys, I tried the iBook open firmware hack on a new radeon 7500 eMac and it works great. I also opened up a new eMac and swapped the cd rom for a super drive and the stock hard drive with a 120 gig one. The inside design of these new ones are completely different, most interesting is the cooling system. It has a solid copper tube from the top of the processor coming around to the front of the board with heat disapating metal fins. It reaminds me of the cooling system on the PB G4. Looks like the eMac is a pretty nice deal when you buy a 20" cinema display to hook up to it.
