selling used servers in bulk

I really don't think there's much of a market at all for used servers. I work at a managed service provider and we support small, medium, and large companies and I can tell you none of the companies we support, from the small mom and pop shops up to the big corporate places, would ever risk their data to a used 5+ year old server. It's just too much of a risk. Especially when new servers really aren't all that expensive. I just priced an entry level HP server with the bare minimum to get up and running (with 2tb drive and Win Server 2012 STD) and the price was right around $2300.

Of course this is very low end but for a small company it would at least get them up and running with a warranty.

So why spend anything on a used server? The risk just isn't worth it.

And yeah, those guys are out of their mind delusional if they think their gear is worth 18 grand.
