Also if you use TPM / full disk encryption for a server in colocation, it only takes a firmware update for TPM to request to reenter the key on reboot.
>But wouldn't it just be simpler to attach a dumpster-sourced monitor and keyboard to the server in question for the 3-4 times a year you brick it?
Maybe it's just personal preference, but I'd much rather plug in a Raspberry Pi than a whole monitor and keyboard. My server is tucked away in the corner without a good desk surface to place a keyboard and monitor.
With the Pi, I can just plug it and go back to my desk and do everything through the browser. It's also nice for when I have to Google things about why it's not booting, I can just do it from another browser tab rather than physically walking back and forth between computers.
