Then you aren't an enterprise because they're absurdly useful for managing dozens/hundreds/thousands of systems.

There's a reason enterprises standardize on a common infrastructure from an OEM that supports everything in the box even though you could go on Newegg and build your own systems for thousands of dollars less.
