As hinted in previous leaks, Apple has indeed revealed new iMacs sporting high resolution retina screens. Alongside the expected 27-inch iMac model with a whopping 5K resolution, Apple also a new 21.5-inch iMac that sports 4K resolutions. Given how new they are to the market, it cannot be helped that some tinkerers would want to immediately pry them open and see what's inside. That's exactly what OWC, a.k.a. Other Wold Computing, did. Luckily, or hopefully, for them, they aren't hindered by an NDA unlike some other teardown experts.
