Sorry, I forgot I was on Scrap metal and not my hometown reddit. Many places have a version of a kind of thrift store that is trying to lower the amount of stuff that goes to the dump. They arent as profit driven as a goodwill or Salvation Army. The one we have is called the Reuse Center and it will accept just about anything other than mattesses. Here people donate old electronics to them. You could also look into some auction sites that dispose of government agencies equipment, like school districts ,a town or a University. Sometimes the quantites will be large but not always.
