Chosen Solution

Hello, as I was cleaning the dust off my old late 2009 mac mini I accidentally broke the lower part of the casing shell on the cable that goes from the power button down to the logic board. I managed to pretty firmly attach the two wires correctly to the board and the machine works fine.

My worry is;

  1. If the dust buildup could cause a short with that little opening without the shell (see the two metal cable ends of the two wires without the casing shell)
  2. Could I easily cover it with something like electrical tape, although the common understanding is that electrical tapes are not ideal for this task (heat & the gooey adhesive they leave behind). What would be the ideal solution if you think I should cover up the remaining part of the partially broken casing shell on the cable? Thanks in advance!

The best solution is to replace the cable assembly (part of bottom case) or at least splice in a replacement connector. Mac Mini Housing - Bottom (09)Mac Mini Power Button Kit (06/07)
