Mini 1U server rack for the raspberry pi 4. Fits the pi 4, a portable 2.5" HDD, a 40x40x20 fan in the rear, and a 40x40x10 fan to blow down onto the CPU of the pi. The cpu fan can rest on a bracket that sits above the pi or can be mounted to the lid of the case.

I'm using a POE hat on the pi for power, so didn't consider unblocking / using the ports on the side of the pi for power, so they're inaccessible.
