Upgrade to Mid 2012 2.8GHz logic board?
Could I upgrade the logic board in this to a Mid 2012 2.8GHz i7 board? I noticed that this (2.53GHz) laptop has only one fan.

It will probably not fit physically, e.g. the 2012 has Thunderbolt ports which yours does not have. Also you would have a problem with the connections from the screen to the communications board (bluetooth, wifi). The cables will be too long or too short. Also the SATA cable will not connect.
