So after setting up my new imac I thought something was odd when I realized it had maxed out in specs. I only upgraded the cpu and gpu but this had 32gb ram and 1tb ssd. The serial number on the box isn't the same as the serial of the actual imac. Do I just keep quiet and enjoy their mistake? My only concern is I want to buy AppleCare In a few months and this machine has it already. It obviously wouldn't allow me to register the Mac to my name since its attached to another Apple ID already. Thoughts?
