I wouldn't see why not if they are the same motherboards & power needed to power the board itself. But I don't know if it's a good idea to try, but I have done it before on Mac desktops, not PBs.
Bump. I've had problems with crossing boards in the 15 inch models. Eg, the ram slot being a quarter inch off and the right side usb having different connectors.
Please someone else input because I need to get one of these since you can't find the 1013 working anywhere.
