I have the last of the G5s in the 20" iMac and this machine has been nothing short of amazing. Alas, I am going to be travelling for the next 6 months and need a laptop instead and would like to, ideally, trade for a Macbook(newer). I already have a 2GB RAM chip to put in the Macbook(wrong RAM, I originally got for this machine). It has 10.4.11 and all updates and I can wipe clean. It is in great shape and I'd even include the iRain 360 swivel stand which is pretty darn sweet for being able to move around the base to show people things.
