My understanding with this project is they also replace the screen and battery with newer parts e.g. higher resolution, or at least that's an option, and all the ports are new (it's a new motherboard). So really the only 'old' parts are the keyboard and chassis. My understanding is there's lots of cheap replacements for the keyboard floating out there given the mass production and the original intention for this device to be easily serviceable by IT departments instead of "RMA everything."
