I did see something called Intel AMT, part of Intel vPro. https://www.howtogeek.com/56538/how-to-remotely-control-your... Does anyone have experience with this? (I have AMD box so doesn't help me) - actually looks like AMD has similar https://developer.amd.com/tools-for-dmtf-dash/

It is possible but extremely tricky to set up AMT headless on a self built Intel. You basically need to press keyboard keys at the right time. Too challenging without a display.
Devices don’t load AMT configuration from USB by default unless a vendor configured them to. In which case the vendor just ships you AMT enabled in the first place.
Better to just image the disk on a different computer.
Then you just have to pay attention to your certs (if you are using https), because browser policy will apply.
I have a boatload of Intel vPro machines spread throughout multiple countries (or the basement) and connect to them both via internet (mutual TLS authentication) and VPN. Never had any reliability issues at provisioning or operating. I had an old AMT v2.1 machine that was a bit unreliable, needed to be manually powered on once in a while or the remote connection wouldn't work.
I wholeheartedly recommend Meshcommander [1] for this.

You could build ~7 devices for as many machines using the article's method.
So I only wanted to point out that there are good solutions out there, even though they might not be cheap. The solution have saved my bacon, and has been worth the money.
Looking at the original project, authentication, mouse support and audio are not supported (maybe in the future?), so if those things are important; a solution like the ipeps might be worth it as well.
But your mileage may of course vary . . . :-)
