Chosen Solution
I was given a Mac Mini that says Model A1283 on the bottom, however it has no slot in the case for an optical drive, and no optical drive inside, but rather there are two, 500GB SATA drives, one above the other in a sub-frame where you pictures show an optical drive. What gives? Update (03/14/2016) Hah! It is a Mac Mini SERVER model from late 2009 http://www.everymac.com/systems/apple/ma…
Depending on what your needs are it makes a nice media server. I replaced both drives with two 2 TB’s. Holds my full music library and vids I’ve downloaded. I have an Apple TV as the front end to my TV.
