Should I buy a used Mac Mini?

Episode 1268 (1:56:32)

James from Austin, TX
Apple Mac Mini

James is thinking of getting a used Mac Mini. How can he find out how old the Mac is? Leo says to check out EveryMac. It will give him a list of specs for it. He shouldn't go back further than 2012, though. He'll want to use the latest version of OS X, El Capitan, so he'll want to make sure the machine can support it.
