Built a nice little PiKVM and deployed it in my NAS. The NAS is heavy and placed in a dark half-height place under the stairs so it’s awkward when things go wrong and you need hardware access.
For those that don’t know what PiKVM is: https://pikvm.org/
What hardware are you using to attach the Pi the PCI slot?
I have a stock PiKMV V3 attached to my home server that seeing this I now need to upgrade!
It’s part of my PiKVM-kit. https://geekworm.com/products/pikvm-a8
It’s also PoE which is very nice.
They also make this one which uses a CM4 but you can control 4 machines! I have been eying it now that I can get CM4s again, thanks for the post!
Not OP, but looks like the Geekworm KVM-A8. They also make a version using the CM4.
