Does anyone have any suggestions on where or how to sell used server hardware?
I'm down in the DC area rather than NYC, but I've sold old tech assets on CL with regularity -- there are lots of buyers out there. It's just that sometimes it's hard to swallow the prices that people are willing to pay.
With so many people moving to cloud-based services or virtual-server setups (or to colos that don't let you bring your own hardware), I think the retail market for rackmount servers has shrunk significantly from what it was a few years ago, when you'd routinely get small companies buying them.
I'm not sure what "the solution" is, or even if there is a problem. But I think that if you have old unused computer hardware, the more profitable thing you can do is simply use it in your business directly and thus avoid buying more new stuff later on.
