Hang on to it if you must. I faced much the same problem here in USA only 7 or 8 years ago. I had a pick-up load, but nobody wanted to talk about anything less than a tractor trailer load. The scrapyards wouldn't take it, and the landfill wouldn't either. It was considered a highly toxic waste. I was getting ready to move 600 miles, and needing to get something done with it, and not risk leaving a pile of "toxic waste" laying around. Finally located a computer recycling place who would take it for free. I'm sure now they were happy to accommodate me in this, but back then I didn't have much choice. I can only guess at how much it was, several hundred pounds, and there were no chinese boards involved, extremely high grade gov't servers mostly, very old/early ones.
But*! if I had only known, and brought it on along on the move.
What I'm suggesting is this, instead of "disposing" of it for little of nothing, why not pack an old shed/barn/semi/etc, until they come offering you top price, which will no doubt be coming your way in time ; )
