Raspberry Pi 4 rack unit
thingiverse
For a small linux cluster test environment, I bought 5 Raspberry Pi 4. To accommodate all 5 Pi's in one rack unit, I rebuilt a 19 inch panel. https://www.amazon.de/gp/product/B075RQMZFC/ I used a sertronics heatsink. https://www.berrybase.de/neu/armor-geh-228-use-f-252-r-raspberry-pi-4-champagner-gold and a USB-C angle adapter. https://www.berrybase.de/raspberry-pi-co/raspberry-pi/kabel-adapter/usb-kabel-adapter/usb-c-3.0-adapter-c-buchse-c-stecker-seitlich-gewinkelt-schwarz So you can easily put the Pi's in and out. It has to be printed in two sections. For smaller printers, the longer left part must be printed diagonally The parts become simply hang in the panel. Maybe you can use some glue.
