For a small linux cluster test environment, I bought 5 Raspberry Pi 4.

It was important to me to build everything in a compact chassis.

On the photos you can see the draft version 1. The download contains the improved version 2.

Unfortunately, I have not yet found a simple and compact solution for the power supply (5V @ 15A) of the Raspberrys. This will follow in version 3 of the chassis.
