A little #minipc#server rack I fabricated a while back. #raspberrypi rockpro64 rock64 atomic pi and orange pi lite 2 all mounted to acrylic I laser cut and powered through GPIO pins. A 300w mini itx power supply powers everything and is connected to a breakout board for easy access to 12v and 5v terminals. Power then goes into multiple terminal blocks. A small network switch is mounted to the bottom as well connected via custom cat 5 cables and 12v PC fans keep everything cool.
