The mac mini 2011 does not fit in the 2010 case. After carefully moving the components to the old case I realized that optical drive bracket did not allow the logic board to slide in smoothly and required some angling to get in in. Then when I was closing up shop I made a second realization that the 2011 logic board simply does not have a place to connect the optical drive to the logic board. I considering doing some soldering but I did not want to risk it. I'm going to just buy an external optical drive and mount it behind my screen. Maybe oneday Apple will include an optical drive again, I mean what kind of desktop does not have an optical drive.
