This is insanely cool. It's a beautifully written article that covers all the major design decisions and issues that affected the final outcome. I'm considering purchasing one for myself and to support the developer. It would be a very cool addition to a homelab or tech/hacker space.
I think my own minor issue is the use of a micro-USB port instead of USB-C - I wonder why, I don't see it mentioned in the article. Maybe adding a PD controller would have complicated the already complex dance of components on the board. Standard USB can supply 5V at 1A (5.0W) no problem, so maybe that was just a simpler way to go.

You don’t need a PD controller. You need two resistors of a set value to be able to have USB-C supply 5V at up to 3A. No ICs needed on the input side.
