Mini Rack 003: ITX Dense Compute with external UPS


Description: For this rack, I wanted to see how much compute I could cram into an 8U mini rack. I would likely add on a better network switch, but the idea is to use an external UPS so every rack space can be taken up with compute, while still allowing adequate airflow/cooling.

The two base units are Mini ITX cases from MyElectronics, which don't have room for a full PSU, so you'd likely use a PicoPSU or use boards that take direct 12V power input.

Above that is a mini ITX tray from DeskPi, holding a Raspberry Pi Compute Module 5 ITX board. And above _that_ is another DeskPi tray, this time for dual SBC, which can also mount two 2.5" SSDs or HDDs below for storage.

(Technically the cluster pictured above was run with mostly CM4, and only two CM5s that I have on hand... But if I wanted to go all out on this thing, I'd go with all CM5, or maybe Radxa or Orange Pi CM5, if my use case worked with the parts of those boards that are well supported.)
