I have a JetKVM (https://jetkvm.com/) and it's been absolutely fantastic. I'm still waiting on the ATX expansion board, but the core unit is used to monitor my homeserver.
I think it would be simpler to buy a network PDU (or iot plugs) for your use case, assuming the computers can be set to power-on automatically.
I'm guessing they're getting through the kickstarter batch and then they're going to launch a store, particularly once they get all the bugs worked out of the manufacturing process.
I kinda would like to see a DP over USB-C version so keyboard, mouse, video, and power all go over one cable.
