I've still got my 2012 Mac Mini with i5 processor. It came with only 4GB RAM, but that was one of the last models that allowed you to upgrade it yourself, so I put in 16GB RAM. It isn't very fast, but I re-purposed it by installing Boot Camp and creating a dual boot computer with Mac OS X and Windows 10 so I can run a few apps that are only available on Windows. It was my first Mac since the early to mid-1990s when I finally gave up on Apple due to their greatly outdated OS in those days. I'm glad I switched back though.
