Thoughts on a case and active cooling for a Raspberry Pi 5 with an M2 HAT (or any HAT, really)

I'm just wondering if anyone has any insight into a good case design with heat sinks and a fan that also accommodates a HAT, such as the new M2 HAT. I'd love to run a Pi 5 with M2 SSD inside a case with a fan plugged into the PWM port. Can anyone point me in the right direction?

Ideally it would look something like this, but be large enough for the HAT and somehow incorporate good fan placement for airflow.

This looks like an interesting solution to my question. It mounts underneath the pi, which means things like heat sinks and a PWM-powered fan would work fine. As long as there's a case that fits this type of setup, it looks like it would work great!
