Uff, converting from usd/pound to euro/kilogram, damn
Checking the best prices here for clean aluminum you could get around 75 cents per kilogram, that would be around 35cents per pound to keep original units. As for the gold extraction, good luck getting the two acids needed in bulk quantities, you need to file a paper with all your info and what you intend to do with them, and as far as I remember cyanide is even banned for personal purchase (not by an authorized company), and if by some miracle nobody is making a call while your paying for it let's see what you do with the gold itself. Not the country of choice to do this.
But if it comes to just a few pieces, rather than smashing it to pieces I will try to grab a recycling coupon for old electronics telling them it's an old PSU or UPS or something, and get that 25 euros discount for a new electronic. It still beats the 500 euros fine for tossing large electric equipment in the normal garbage bin!
