That acrylic case for 99 dollars?? That's kinda ridiculous.
I guess that includes a power supply but it looks like a
very basic one, plugs into the barrel jack instead of the
ATX socket.

I would not be surprised if a full GPU load on a reference
RX 480 card just melted that power jack :)

Actually having a port is not a bad idea, there's edk2
for virtual machines (OVMF) already.

It's actually always recoverable. The boot ROM can always
boot from uSD and even from the serial port (!):

(the docs are from another SoC but it's the same here)
