Do these Mac mini's have the same SATA/Power cable as the same year 13" (and possibly 15" and 17") MacBook Pros? Back when I had my Mid-2012 MacBook Pro, I remember people saying to swap out the SATA cable with a known good one (or a new one, which is presumed to be good) and see if that fixes it. Not sure if it will do anything/apply here but just wanted to give my 0.02.
