Is this Mac Mini useful for anything?

I explored this question a few months ago when I came into possession of a Mini G4 as part of an eBay bundle that I wanted for another item that was in the bundle. I came to the conclusion that the Mini itself was not worth finding a use for or investing further into, and resold it.

we use a G4 mini hooked to a projector via DVI to play DVDs and iTunes movie rentals.
