Aside from the logic board differences, there really isn't much else that makes this machine different from its 15" Unibody ancestors.

Small plastic plates adhered near the display hinges seem to keep the display data cable and antenna cable bundle stationary while the display is opened and closed.

The SuperDrive used on this machine has the model number UJ8A8, making it presumably different from the model UJ898 used in the Mid 2010 15" Unibody.
