Over the long term, you could even see miners taking care of their cards with a view to maximising the resale, and cultivating a good reputation for customer service (i.e, testing used cards before shipping, and refunding or replacing cards that slip through. Such a reputation would allow them to charge a little bit more for their used cards, and to sell their stock more quickly than competitors).
There is enough discussion online about the reliability of used mining cards to suggest it's far from straightforward. Some mining card are overclocked, some are underclocked for efficiency, some just have their VRAM overclocked. Since miners themselves don't benefit from having a broken card, many are careful about good cooling, perhaps more than a teenager trying to maximise their frames per second in Death Kill Auto 3.
