Other than a server I can't think of a real use for it as it won't be able to play HD movies will it? So it's no use as a HTPC. I'd sell it eprsonally.
They're pretty power efficient so it would probably work well.
I have found a board that converts a sata drive to IDE and I could remove the optical drive and fit it.
But I'm not entirely sure i need a media server though!
