Question for the techs in the audience. I have a 2012 MBA (i5,1.8,4GB). Could I buy a 2012 i7,2.0,8GB logic board and swap that into my Macbook Air? Is there a technical reason why I couldn't do that? Does the serial number follow the software or does it follow the logic board, or some other part? I really want to upgrade the RAM basically, due to my usage of VMs, and since I can't add any more RAM, I wonder if I could just swap the logic board. It's probably easier for me to tell the laptop and buy another one with the specs I want, but I was just curious as to whether it was possible, and whether any one here has done just that.
