Raspberry Pi modular rack mount

Yet another design to mount Raspberry Pi computers in a server rack.

I wanted something fan-less. So this design is based on using Raspberry 4B boards in fan-less Argon NEO cases, together with fan-less UCTronics PoE HATs. Not a sound and temperatures sit between 49℃ and 52℃.

You can fit up to four devices in a standard 19" rack or two in a half-rack (using the spacer).

There is also a blank which doubles as a tray for e.g. power supplies or SSD drives.
