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/
I think some other CPU/MBs also have this feature.
But I would giess they are only implemented in business scopes like the Pro/EliteDesk line from HP and the other SIs equivalent.
