@lopta @spacehobo @futurebird @oxidecomputer to me the most impressive part is where they completely replaced the BIOS with their own firmware, written from scratch in rust, that is co-designed with the kernel.
But also, close to OP's point, they designed the rack so that the owner never does any cable management within the rack. E.g. when you need to add another motherboard, you just slide it into an empty slot, and the back of it auto-connects to DC power & network cables.
