Acquired Some Elan Components, What are They?

I just acquired the following pieces of equipment and would like to know if these are worth keeping. To be honest, I'm not really sure what these are used for. From top to bottom:

Elan SS1 System Station
Elan Via DJ II
Elan S86AV Integrated Multi-Room A/V Controller
And there is a Nokia N800 remote control but I don't know which of the components it works with.

Anyone have any ideas what these would be good for? I just have a simple stereo setup, nothing fancy.
