I have a server that doesn't do anything at all. It has neither inputs nor outputs connected to it, and isn't even connected to a power source. Except that I suppose I'll still have to blow the dust out of it every so often, and make sure it's in an environment where it won't rust. (To be less glib: what do you mean by "system"? What do you mean by "maintenance"?)
