Don’t do this. Don’t spend your money until we come up with some better way.
Given the Waveshare CM3 to Pi 3B adapter, which mounts the CM4 on the bottom, it just plain does not fit. @Tom-B, above had to cut a whole in the bottom of the laptop the full size of the CM4. From my efforts to just squeeze it in somehow, I think he’s exactly correct about this. There are several problems, but the big one is heat. It can’t use any heatsinking from the metal bridge, and just cutting a hole in the bottom isn’t going to allow convection.

I was hoping to get it to just fit and then buy some aluminum sheet material to make a heat spreader across as much of the case bottom as I could. That’s how the pi-400 does it.
