Why not combine the ATX board and the unit itself, and have a real HDMI port? This seems like a mess of cables and dongles.

The KVM can be plugged into any system not just those with a spare PCI-e and you can move it around easier without having to bring systems down if you don't need the direct power control which is the main use case of the PCI-e board.

Something like the NanoKVM-PCIe? I have both JetKVM and NanoKVM-PCIe, its nice to have options.

Yea, just looked at this based on the recommendation in the other comment, it's exactly what I was looking for. Hopefully the software holds up/stays maintained...

I do think that JetKVM software is more polished, and has more frequent updates. Stuff like streaming images over the network is something that is handy.

Nano KVM commits have stagnated a bit, but the form factor is really nice to have everything tucked away. I wish I could run JetKVM on the Nano KVM.
