I was hoping someone can help shed some light on the main differences between a mini from mid 2011 with 2.3ghz i5, 4gb memory, 500gb drive in comparison to the current model with 1.4 ghz i5,4gb,500gb drive. I plan on using the mini as a media center front end running plex but also acting as the server running plex media server pointing towards a Unraid server. I need it to be able to stream Bly Ray rips and dvd rips to the mini itself, iPads, iPhones, ps4 and a Apple TV outside of the home. Not all at the same time. 2 at the same time 3 max. I just purchased the new mini but maybe able to get a good deal on the mid 2011 of its worth it. This will be a long term solution.
