This one has a lot of RAM so easy to set up a sizable RAM-disk which I like for avoiding cluttering my SSD with stuff I can't easily erase. Most of all it appears to have a better air flow through the back component section which I'm hoping will prevent it from over-heating and shortening its life span as the two previous AiOs seem to have suffered from (I'm in a very hot climate area and can't use air conditioning due to allergies).
