Similar experience here - everything was easy peasy but dropping the new drive back in was tricky because I couldn't get leverage to lift up the left side. With both the antenna plate and the fan still attached, it was hard to hold the mini vertically to let the new drive drop in. I just unplugged the fan and set it aside instead, held the Mini vertical and then wiggled in the new drive. It lined up pretty easily and I was able to reattach the connector and then plug the fan back in and proceed to reassembly. The antenna plate slid back in the same way it came out and I applied minimal pressure to get the last screw hole to align and it snapped into place perfectly. Whole project took about 30 minutes - including having several colleagues come by my desk to chit chat and distract me. Thanks!
