What I do if I have a massive stock pile of junk is put it all on ebay. Throw together a reserve of like 400 bucks and make them pay for shipping. Hey it's free money. Sounds like it too late for you though because you already dug them a grave.
you could just do what the othe people said....just give them to a school or ship them to a country in need.....or you could try to use the old parts and either remake them or sell them...just a thought, i gave most of my spare parts and cpus to an old elementary school
