My macbook recently died. Well the screen did and the guy at the local warranty center was a jerk and wouldn't call it warranty even though he could have. So now having to buy a new mac I looked at used and found this G5. I never used one so I don't know wither it's any good or not. If not im going to just get a mac pro. Can someone let me know. http://classifieds.castanet.net/showproduct.php/product/737730/cat/950
