During reassembly, the SD Card reader end of the I/O Bezel will not go back in flat like the AC power connector end, thus the SD Card reader end protrudes about 0.5mm from the edge of the back of the MacMini, I tried took it out and put it back in many times but could not manage to push it all the way in. The truth is it is hard to notice and everything else works fine but it is annoying to see that tiny bit protrusion. Anyone else had this problem? or it was like this already before I took it out? i can't remember what was it like now.....
