Moving two USB ports and the headphone socket to the front is a long-overdue improvement. Not so sure about putting the power button on the bottom That wouldn't fit in with my current setup where I have two stacked Minis and an (even smaller) HP Mini PC stacked on top of them.
What a strange place to put the power button, maybe they think people will not use it that much.
Saying that, my Mac mini is normally left on, it is only when I take it to my partner place that I turn it off.
A bit small that new Mac mini, I would be worried about it over heating with little room for air to move around.
