Is any of this worth keeping or trying to sell?

My parents own a rental house and had an audiophile as their tenant for a while. When he left, he left several items behind. I wonder if any of the more seasoned experts on here have any idea whether a box of miscellaneous items I recovered is of any value or should merely make its way to the curb.
The items I found are:
A spool of Van Den Hul digital interconnect cable
A Naim 5-4 pin cable
A Naim 5 pin-FireWire cable
Some Monster cable (RCA), varying lengths and gauges
An RTI remote, in the box with manuals
A Linn Sekrit (just one) in its box.
Some Linn Aktiv cards (marked Ekwal)
Some Bose Personal Music Center II remotes
A Bel Canto Homre Theater Master touchscreen remote

Any help would be appreciated.

Thanks in advance!
