Well, since I've read people saying they've used controllers from them on real model m's I'd say yes. Anything but the actual keys would be my guess.
Although, if that's what you want to do, I'd buy the rubber domes first. Then taking out and setting aside the useful bits (like the controller). After that, talking to customer support, and mailing in the case and whatever else they want/need to build you a new board in the old case directly. No sense getting one of their cases if you ain't gonna use it.
