So I have been tasked with replacing a dying Tower server. I need 2 servers to act as Domain Controllers and another for an EXSi server. Hardware is not my strong point and there is a ton to choose from. I know I don't need anything too beefy for the DC`s but the EXSi will. So what are your recommendations. I know I will be spending 2.5K on both DC`s but the ESXi server I am not sure. Need to save money with this build.
