First pic is a board connected to the power supply board. Should I break the power supply side off? It does add a lot of weight though .

Second pic is 2 cpu's I am not sure what to do with. any help identifying? Is that a cpu on that board?

Thrid pic is loaded with cpu's? Not sure about these boards, I have about 8 of them. I pulled the small gold cpu out of the board on the left (see the empty socket)
