I suspect we will see something very close to the MacBook Pro motherboard layout, but without the cutouts allowing it to be more square. I wouldn’t be surprised to see very similar fans as well. The efficiency of those fans is likely to improve with a larger volume of air above them.
Acoustically, two fans allows for lower noise levels. They can do clever things by mismatching the speeds to avoid sympathetic whines/hums etc
I cannot wait for this next mac mini!
As a macintosh fan I jumped into the Apple Silicon bandwagon with my current M1 Mac Mini, but I need more power/ram for my job and the M1 Max is the sweet spot for me.
More power would be nice, but not strictly needed.
I tried the macbook pro in late 2021, however (as lovely as it was) I found it way too expensive and unpractical for my needs...
Consider I don't travel much...
In the end I did the smart thing and I sent it back, waiting for the M1 Max Mac Mini.
I really hope it'll be released at the March the 8th event and, to be fair, it wouldn't make sense any other way.
Apple has to release all the M1 derived chips before the M2s will arrive in Autumn, so (considering the almost confirmed delay of the new iMacs) releasing the high end mac mini in early march would be perfect.
Whoever wants it will purchase it then, and there'll still be plenty of people willing to get the imac, in summer.
It's perfect.
The high end mac mini would also make the first 2022 Apple event juicer, as it doesn't have any groundbreaking products planned so far.
The iPhone SE is rumoured to be the same design as the 2020 one, the new iPad Air will be quite similar to the previous one...a redesigned mac mini would be the perfect cherry on top.
