I have some cheap rackable server w/o KVM feature and I was ready to order an ASROCK Paul https://www.asrockrack.com/general/productdetail.asp?Model=P... but looks like I will definitely go for a PI KVMs
After all, hardly any point of having a open-hardware HAT if you connect it to a closed-hardware Raspberry Pi. Even if the full schematics etc were available, the processor on the Pi is anything but open.
