Late 2012 Mac Mini Second Hard Drive Install

My Problem

I had installed a 500GB SSD in place of the original HDD. A few days later I realized I could put the HDD back in the mini as additional storage.

My Fix

The upgrade went flawlessly.

My Advice

You don't have to actually unplug the WiFi antenna. You can set it aside and then snake it out of the case when you remove the main board.
