Raspberry Pi 4 Cluster Case with POE Hat - No extra bolts

thingiverse

I was having a tough time finding a Pi 4 cluster case specifically designed for a UTRONICS Power Over Ethernet (POE) hat, which led me to design my own. It works seamlessly with the UTRONICS POE hat and requires no additional hardware beyond what comes with the hat. I opted for the POE route because it simplifies connectivity - just one cable per node - and allows for easy on/off control via managed switches. If your printed mounts aren't perfectly rectangular, sand them slightly to ensure smooth assembly; don't overtighten them. The fan is an Arctic F12 (available on Amazon). If you need to buy additional hardware, consider a kit like the HVAZI 320pcs M2-5 nylon hex standoff assortment. For each node, you'll need four 8mm standoffs, four 2.5mm nuts, and four 2.5mm screws. My cluster consists of twenty nodes, including my main machine's four; I use the Pi cluster to enhance my primary rig.
