Anyone with "store" connections? Looking for store model Mac Pros

I work with a non-profit, and we're pinching our pennies.

I'm surmising that at some point in the future, a memo will go out that says - take all the 'old' mac pro display models the showroom floor. I imagine these will be sold as refurbs to general public, or offered to employees at discount etc.

Anyway I can get in on the action for best price? Perhaps units with banged up cases... ?

Thanks for the input!
