I want to create a Hyper-V server for my lab at home. It does not have to be a 2012 version. What are the spec requirements (cpu, hard-drive, etc...) for a decent server? I want to be able to create a mixture of 5-10 servers and clients. Also, I would appreciate suggestions on where to buy a used server to meet my objective and approximately what it would cost?
I briefly looked at train signals video on setting up a Hyper-V lab at home and it mentioned he had 2 servers. Will I need two servers to accomplish my goal?
