“It's a great bit of kit. The top lies flush with the USB ports. The bottom adds about 7mm from the PCB. There are cutouts for all the ports on the PCB, and all the IO ports on the side are unimpeded.
It gets quite warm to the touch, but I think that highlights how much something like this is needed on a Pi4.
The only issue I have is that this isn't ideal as a computer for use on the move, as the SD card still sticks out slightly from the side, and the GPIO pins could get bent if chucked into a bag. For that use case, the Argon ONE case is much better.
However - if it's just going to sit on a desk somewhere, then I can't think of any improvements.”
