It’s been done before via Axiotron’s Modbook, but it’s being done cheaper.
Per PC World, older MacBook owner Matt of Enigma Penguin took it upon himself to convert the MacBook into a touch-based tablet with interesting results.
After taking the MacBook apart and removing non-functional hardware, Matt ordered a third party touch screen.
