As you can see the most important resources is RAM with a gigantic amount of 3TB, for the OS as long as you can run docker I think you are fine but most BP tend to pick linux

check this question for more information, there is lots of link for articles about the hardware and configuration of BP What is the system requirements of being a block producer?
