Chosen Solution
I’ve been reading and watching how the motherboard of a Mac Mini with an M1 chip can actually be installed in an iMac from 2011. May I ask if it’s possible to install it in an iMac from late 2012? Is the body large enough?
If you watch Luke’s video he gives you the blow by blow conversion of a 2011 27” model. While this is a fun project since Apple is presently not offering a 27” replacement after intro’ing the new Studio system the other day. I’m not sure if you can modify a 21.5” system and the 2012 series is even thinner than the older 2011 and older models. If your 21.5” is still working I would hold off doing this. I would sell it and just buy a 24” model vs buying a M1 mini to then convert it.
