Looking to buy a used 2012 Mac Mini that I can upgrade with 2x 8g RAM plus 2tb Samsung SSD and connect to an Apple Display. Will this work ok, and what screen resolution is the older Mini model capable of outputting? Will I be able to obtain full screen resolution on the latest Apple Display? Apart from web surfing, will mainly be used for home sharing music and movies, Lightroom and transcoding video files. Will this set up be ok? I understand that any later model will not be upgradeable? Any cheaper options?
