I have a guy who runs a profile selling old hardware on the country's most popular 'craigslist' site. He has a garage full of PC stuff and is 160 miles away. And is not shipping anything large via post.
And that's it. The region where I live in has about 800.000 people, there is not a single CRT monitor on sale anywhere. If one does get posted, it's a POS monitor.
I think everyone dumped everything they had when housing started surging due to tourism. You'd be lucky to find a shed that wasn't converted for airbnb. POS monitors aren't random, they're still out there from those restaurants and bars. Everything else dumped long ago.
Due to rising pressure on waste management 99.9% of companies are in vendor programs for desktops and laptops, they don't dispose of old items, they return them.
Possible there was a window when vintage junk was being thrown out rapidly, but it was a fairly long time ago, before I took interest in this. Since then generations of junk have been swapped and the latest junk is just stuff few years old and mostly commodity items that you can associate with rentals or tourism activity.
Just dropping this here because I think local availability of vintage components is tied to storage space directly. If you have options today, act on them.
