Huh? Seriously?not goodwill, they don't set out older PCs since they have a deal with Dell taking them away.
And yet they have piles of CRT televisions.That's really weird.. I have recently taken bad & empty chassis & CRTs to goodwill. -- they don't set them on the shelf no matter how good they look.
It's something to do with EPA regulations and fines for disposing of electronics with hazardous material (CRTs are loaded with lead in the glass and some part of the computer or monitors have mercury). So it's more of a liability instead of being overwhelmed with hundreds of unwanted or broken CRTs that they'll end up having to pay $5 or $20 to dispose of legally they just say they won't accept them. e-waste is a huge problem with all the throw away electronics being made today. Cell phones are a huge problem just themselves for the same reasons.
Have you tried posting them on your local craigslist though? One day isn't very long to get responses but since they aren't vintage but are huge I'm not sure how much interest you'll get :-/
I once heard a panic about all that phosphorus getting into the groundwater from discarded CRTs. There's no phosphorus in CRTs....
St. Vincent de Paul here has computers and all related peripherals for sale when they get them. It's great.
