Question about grading motherboards, I'm new to scrapping electronics the right way and have read as much as I could find about grading motherboards. I read that they're graded by the CPU chip socket thing but was wondering if color had anything to do with grading them as well. I took a few, (not more then 10 as im not a big e-waste guy) to this one yard on my way to work and they said that mother boards get graded as mid grade boards unless they're green on both sides. Does this sound right to you e-waste guys? The yard I took them to is mainly a steel yard that actually rivials the yard I work for 3 miles down the road so I don't really think they know much about the E-waste either. Its just convienent going there since I drive by them to get to work anyway. Also whats a good scrap price for CPU's? That yard said $5 a pound so I kept all the gold bearing stuff till i heard from an bigger electronic scrap yard.
