This is my dev&test platform containing 6 Raspberry Pi 4. They are connected to built-in network devices which setup a VPN-connection to my home firewall.
Hardware is covered by an acrylic hood holding two fans for cooling.
If somebody is interested: I could of course share all the necessary STL-files and a part list (e.g a huge Ali-Express basket), just let me know.
