I use IPMI on many of our servers, you get access to the console and you can control power on the system as well. There are some motherboards that support add-on cards. I usually use Supermicro motherboards and you can get them on the Atom series and up processors. The great thing about the console, it is like logging on directly at the system and not via an RDP session. I will be putting together a dedicated box for BlueIris (or whatever I use in the future) with IPMI. A great thing about it is, you plug the box in and you can install the OS and everything from anywhere with access to the IPMI. It allows you to use virtual devices such as an ISO, CD, DVD, etc located on another computer.
