I lucked into 8 oldish servers from work. Tore one apart to see what was in it that everyone always desires to get.... Some nice pieces in there.... However, this is a picture of the metal pieces that are inside a scuzzy drive, one at each end. I was going to heave them into the metal bin but when I picked them up I noticed the density. They are very heavy for their size. As you can see I filed a notch but they are not plated. Chrome? Stainless? Anyone know what they are for and what they are made of? Thanks in advance.....
