I have a spare Pi4 sitting around the house that I could pretty cheaply turn into a PiKVM. Looks like there are some slick hats to install into a PCI-E slot so I don’t have a Pi and a bunch of wires hanging out in the chassis. Looks like I’ll be going that route. Just need to figure out how to power it (they all seem to require external 5v or POE).
