I have a late 2009 Mac mini that I bought in March. 2 weeks ago I tried to use an apple remote with it and it would not work. Apple change the IR board on the mini. After 10 days I picked my mini up from the apple store and I noticed 4 marks from when they opened the mini. Ripped aluminum gouge marks on the bottom of the case, the back of the case by USB port does not line up anymore. I brought it to there attention but did not make a big stink and left. I have open a few mini's before (not this one)and know how it is easy to mess up. When I got home I tried to use my bluetooth devices and they would not work, I tried the magic mouse, track pad, KB. I called apple to trouble shoot and they said I have to bring it back in for repair after 20 minutes of trouble shooting. I guess I'm going to be looking at another 10 days without my mac. Do you guys and gals think I have any grounds on asking for a new unit, since they broke something in the repair, and put those marks on my mac mini case?
