Its a bunch of old crap. I consider myself a 'stopped before it was too late' hoarder. A lot of stuff which may seem useful when collected just ends up gathering dust and getting old.
I love to get stuff. However, i also have a rule: whatever i have not touched for a year, it goes straight into the trash bin, if no one else wants to have it. After all, not using it for a year means that i'm unlikely to have a need for it in the next years to come. And if, then i can get another one any time. Sure, with some old, fine equipment that might not be so easy, since those units simply will die some day or another, and thus get rare, but they are nothing that could not be replaced by more modern units either.
But especially for parts and similar stuff, i usually simply throw away things after a year if no one else wants them. Heck, how many nice enclosures i had over the years, from old telco equipment and the likes. Sturdy, well made, etc. But no point in keeping them if there is no use for them. I already have enough stuff as it is. But i can somewhat understand folks who hoard such things. I'm rather close to that border myself sometimes.
Greetings,
