What the heck did the boards from photo 4 come from? This is my opinion, and im not very good at grading boards, other than the obvious low and motherboard, ram, etc. Anyway, I would pull the gold pins off the first one, and toss the board in low grade. Second board, I would say high, or maybe even low telecom. Photo 4: I would try to sell them on ebay for gold recovery, if not, like super high grade, but idk. And last one would be finger boards. Idk about the heat sinks. I would leave them on to be safe.
