I have a late 2012 Mac Mini (2.3 GHz i7, 16 GB and 1TB hard drive, 500GB Samsung T5 external SSD) connected to a Thunderbolt Display. It pretty much just sits in a spare room and doesn’t get any use. I’m trying to figure out if there is anything I can use it for. Maybe something I’m not thinking of. Or, if I should sell it. In that case, what is it worth?
