cpu memory worth anything?

you go to your scrap yard or any carbide scrap dealer or your local recycle station and they take metal.
Call first, often they also require a minimum amount like 50pounds, but I suppose if you are just a kid, they may just give you the $1.50 so they don't feel like a jerk.

If you've done the math, You are better off sorting through trash and getting the bottles/cans for recycling as 20 glass bottles=1laptop heatsink. And 20beer cans/bottles are much easier to obtain then a laptop.

Or selling/donating the laptops whole (donations will give you a tax writeoff). Or selling it as-is on ebay for people who may randomly want to use yours for a project of some kind or as scrap parts.

oh final note,
Most places will consider a computer (or other electronics) e-waste.
And charge you a fee to take it, rather then the other way around.

You cannot just throw a computer into your trashcan it is not good for the environment.

Although, there are places who will accept it for free (check your local recycling guide).
