I scrapped several hundred older computers, servers etc. At that time the scrapyard made sure there were no boards in them before you unloaded, since they were classed as toxic waste. I was needing to clean up this mess before I moved, and broke it down as best I could. The steel I could take across the scales, the plastic I could hide in heavy duty garbage bags and drop it off at the city waste site (thanks to a suggestion from someone who talked on the phone there), a few monitors went into my landlady's dumpster at their jobsite (when there was room left), but a daunting pile of motherboards seemed to be unwanted anywhere, and I didn't want to be the culprit of abandoning toxic waste! Finally talked to a computer recycling place there in town, who would be so kind as to let me drop off these gold laden jewels for free! Which I did, a lil Ford pick-up truck bed nearly full. Oh Well!
