Server grade components tend to be constructed for more rugged continuous usage. While you can obviously succeed in obtaining low power hardware, you will lose much in terms of redundancy, over engineering for wider tolerances, higher internal temperatures, etc. -- Craig White <craig@xxxxxxxxxxxxx>
