Cisco Catalyst 4507R+E complete units w/ ws-x4548-gb-rj45v 48 ethernet port modules.

Hey everyone, new to scrapping and found a source for all sorts of big Corp. E-waste such as these cisco catalyst and more. I want to maximize my profits obviously but not sure if they are worth trying to resell or breakdown.
Not a computer wiz by any means but the price range for these online varies drastically and therefore I'm not sure where to go with this. I cant tell what condition they are in, if they work or not, or how old they are, but they were free so...

I have 4 cisco 4507R+E units and 2 4510R+E units with all the modules for each unit.

P.s. wont let me attach pics file size to large. Will try to post pics soon.
