There was one time I had to drag a monitor and keyboard to the server though, when I had disabled the LAN. A possible upgrade to your product could be a 4G modem for remote control. And maybe a small battery so it could send a warning SMS on power failure, as well as gracefully shutting down the server, and later push the start button when power come back.
