Good point mas.
But the “extra” Mac would be running anway (I like the convenience of having a networked machine in the kitchen so that I can track the family calendar and to-do lists, see the latest newspages, etc.)
So by using this as a server too, I’m actually arresting the further proliferation of energy eating appliances in the house. No?
As an aside — how much power consumption are we talking about here? I know that any un-needed consumption should be avoided, but compared to the fan in my furnace/air conditioning (which runs all day) and the pump for my pool (runs May to September), is the difference between a PC and a NAS device really material?
