The Cuboid Lab - Custom aluminium & acrylic mini rack/case

I wanted to eliminate all the Raspberry Pis and messy networking cables by consolidating everything into a clean and compact setup. The result is a 20x20x30 cm custom enclosure that houses three mini-ITX motherboards, each equipped with an Intel i5 8th Gen CPU, 32GB of RAM, and a 1TB NVMe drive.

Each motherboard features dual Gigabit Ethernet ports, all connected to an internal 8-port network switch. Two of the switch’s remaining ports are routed outside the enclosure and connect to my main switch, currently configured as a LAG trunk group.

The goal of this setup is to enable the creation of various network topologies within a 3-node Proxmox cluster. I run extensive tests with firewalls and Kubernetes, so having virtually unlimited VLAN-aware segments to experiment with has been a game-changer.

If you’re interested or have any questions about the build, feel free to ask!


This issue documents a completed custom enclosure and Proxmox cluster rather than requesting a repository change. No files, tests, or entry points are identified, so a contributor would first need clarification of the intended change and what completion should mean.
