Can a 2014 Mini work as a home server as well as the 2012 with dual HD? I like the idea of the 2012 having dual drives so I can use it to back up laptops on the network. Will an external drive connected through USB or TB work as well as the internal drive on the 2012? I use a laptop and iPad most of the time. The mini will be used to encode movies occasionally, sync iphones/ipads, and print server. Nothing heavy duty, so I don't think I really need a quad core from 2012.
