I've had them listed on FB Marketplace for months. In that time, I've sold four (3 to one guy, one to myself), and still have 20-ish more.
i5-13500E, 32GB DDR5, 512 GB NVMe, scratched and dinged a bit for $500 is practically a steal! Hardly anyone's biting or clicking, I don't get it...
New open box models (not scratched and dinged), if anyone's interested: https://www.ebay.com/itm/188355326179
Edit: they're intended to be retail POS PCs, like cash registers. (The motherboard literally has a header for a cash drawer!) So unless you're a particular kind of retailer, you're not asking your distributor for them. If distributors aren't looking for them, our B2B buyers aren't buying them. If they were Elite/Prodesks, Optiplexes, or Thinkcenters, they'd probably be gone by now.
Why don’t you part them out? The market for the parts will be more liquid. You might sell faster and at a higher price. You could try doing it once and see how it goes.
I've seriously considered doing that. Since they're still under warranty for another year or two, I've decided not to... for the time being.
I assume you're not in the Seattle area?
Edit: Pittsburgh
That assumption is correct.
