KVMs are unreasonably expensive and my work was about to throw this one in the dumpster. I just need to order some console cables first but I'm really pleased.

PiKVM?
350USD? Yeah not that cheap either...
Roll your own 😎 lots of folks have a pi 2 that's not doing much
...How? Yeah I have a Pi3 and a Pi4 lying around without much use at the moment. But how do I handle the inputs/outputs etc?
HDMI to CSI Camera Adapter. Then you hook it up with PiKVM. https://docs.pikvm.org/v2/#required-parts
I have IPMI and web interfaces for most gear, I just don't want to have to carry a laptop in every-time I need to tinker.
I also have a bunch of AV switchgear and it would be handy to adapt a multiviewer to one of the VGA ports for monitoring that side of things too.
If you're comfortable with it, an analog (non-networked) kvm switch can have its button connected to a single input Pikvm via the GPIO. You visit the PiKVM's webpage, hit a button and you're now connected to a different machine.
If you have a raspberry pi 1 or 2, this isn't very expensive, but nets you an open source IP KVM.
