I have yet to cash in any boards...i talked to a local company about their grading and pay policy, he told me they have high and low grade. I told him ive been pulling aly heatsinks, motors/transformers, and anything with copper on it...he told me i didn't have to, just pull the board and thats it. I know they obviously want to pay as little as possinle, but for motherboards what all needs to be on/removed? Do buyers care if copper is pulled off?
