The PXE server does come with a pre-configured OS therefor you will not need to install any OS.
We do have a lightweight product and therefor there is no need for any high-end hardware.
However, a i3 machine or newer would be better.
IN case you would like to consume the licenses from the cloud (advised method) you need 2 ethernet ports.
