Human: High-Tech Raspberry Pi Enclosure for Multi-Machine Setup. Parts Required: * 120mm Computer Fan, 12v Power Supply - https://www.amazon.co.uk/gp/product/B07RQHL251 * Network Switch - https://www.amazon.co.uk/gp/product/B00VTI8K9K * Micro USB Cables (5-pack) - https://www.amazon.co.uk/gp/product/B07BGT9KWJ * Short Network Cables (4-pack) - https://www.amazon.co.uk/gp/product/B00VC03Z7C Tools Required: * M5 12mm Screws (for Fan Mounting) * M3 6mm Screws (for Case Walls and Pi Mounts) * M5 Screw Tap * M3 Screw Tap * Drill Bits: 2.5mm, 3mm, 5mm * Network Switch Modification Kit Drill out screw holes with 2.5mm drill and tap with M3 screw tap. Be cautious when drilling on Pi racks. I used a 2.5mm drill for each mount, followed by a 3mm drill for the initial couple of mm before using the M3 tap for the rest. The fan was tapped around its mounting holes. The front wall can be made from clear acrylic to showcase internal components. Cut a 3mm thick piece to match the rear wall section and drill/tap necessary holes. I chose the network switch due to its ease of modification. I drilled a small hole in the case, passed a USB cable through, and soldered it to the underside of the power socket. Since it's only 5v, you can use the fifth USB socket on the Anker power supply instead of a separate supply for the switch. The fan was connected to the top Pi's GPIO pins (pins 4 and 6) at 5v and gnd. It runs slowly due to its 12v design but provides sufficient airflow while remaining quiet. Two versions of the base are included: one with corner walls and one without. The latter requires printing corners and supergluing them to the rear and front walls, best done after screwing them in place for accuracy. This project is still a work in progress (awaiting acrylic delivery). Raspberry Pi cluster mounts were sourced from https://www.thingiverse.com/thing:2994509 and modified with screw holes instead of pins. Unless you prefer to glue everything in place, consider adding foam on top to keep the case lid secure. Fan grills can be found at https://www.thingiverse.com/thing:298648; any 120mm grill will suffice. Double-sided foam tape or 3M pads are recommended for securing the PSU and switch in place. The enclosure can be painted afterwards, but mask off areas where glue will be applied and use a good primer/filler paint first.
