Seagate Goflex Net as a UPnP Music server?

Hi all

I was thinking about buying myself a new Rotel setup, including their new RT-12 network streamer/player.

And then i was thinking about if i could use my existing Seagate Goflex portable disk with one of their NAS docking stations called STAK100 (or 200) as a UPnP Music server, would be hopefully an easy and inexpensive solution.

However i cant find much info online if anyone have had success with this. So maybe someone in here has some experience or have heard something?
