> the last set will end up at the ewaste recycler, because who could I find that wants that old hardware?

You might be surprised. Living in a large city, everything I have put for sale has found a new owner. Old and seemingly useless computer hardware, HDMI cables that don't support 4K, worn-out cutlery, hairdryer that's missing parts, non-functional amplifier, the list goes on. If the price is right (=very low), someone has always showed up in person to carry these away. And I'm always very upfront about any deficiencies so that they know what they're getting.

I'd say a common profile for the new owner is young people who have just moved and are on a shoestring budget.
