Selling Nortel BCM50e Equipment, Is It Worth It?

I am cleaning out a client's computer room and came across some older equipment such as a Nortel BCM50e that is part of 4 devices. Picture included.
My instructions are, to sell it, or if I can't get at least $100 then send it to a local recycling firm.
Is this worth my time?
Does anyone know of another website to sell equipment on?

Sadly, there are no power supplies for these devices.

Thanks in advance!
