New iMac innards revealed by engineer showing the 'chin' to contain the M1 logic board

Apple’s new all-new iMac is finally here after extended stay of several years for the previous design. At just 11.5 mm thin, it is pretty easy to understand why Apple had to wait for its new M1 chip to be ready before Apple could build an iMac like the new model. While it comes in multiple colors as expected, it was also expected to arrive without a ‘chin’ and look something more like an oversized iPad Pro.

Instead, the chin remains intact (albeit missing the familiar Apple logo on the front) and has sparked quite a bit of comment on the blogosphere. Now Apple iMac engineer Fiyin Adewale has taken to Twitter to post a couple of shots of the iMac’s internals revealing that the chin hides the entire M1 chip and logic board. Of course, Apple could have built this behind the display, removing the chin, but in true Apple tradition, it has instead decided to make the new iMac as thin as possible.

The shots posted by Adewale also reveal what is in fact hidden behind the new 4.5K display panel which includes the various interconnects as well as the large speaker chambers. This is all extremely customized, tidy and well organised in a way that most other OEMs would simply never bother with. There’s also a couple of small fans on either side of the motherboard, revealing that it is not passively cooled like the M1-powered MacBook Air, but actively cooled like the M1 MacBook Pro and Mac mini.

The new iMac goes up for pre-order at the end of the month and will be widely available in the second half of May.
