OK, I went outside and broke down some hard drives. The first four that I did, I took some weights and made some calculations.
I will list the weights individually then totaled for the four of them
Start weight
1lb 3 oz, 1 lb 4 oz, 1 lb 2 oz, 1 lb 2 oz total weight 4 lb 11 oz at .70 = 3.29 minus shipping
Boards
1.2 oz, 1.2 oz, 1.8 oz, 1.6 oz total weight 5.8 oz @ $3 per pound = $1.08 minus shipping
Platter(s)
1 oz, .8 oz, .8 oz, 1.1 oz total weight 3.7 oz. @ $2 per pound(e-bay) about 50 cents
Aluminum
10.8 oz, 13, oz, 10.2 oz, 12 oz total weight 2.875 pounds at .65 = 1.86
total $3.45 after break down for those items. Not a giant difference except for the shipping. If you are small time shipping is of concern, if you are shipping gaylords full of them then the shipping pretty much does not matter to you as you will get a higher price that mostly makes up for the shipping.
There is another variable here. The magnets. In bulk they fetch almost 50 cents a piece as can be seen in the following link. Apparently they are used for windmill stuff.

Of the ones that I tore apart, All had 2 magnets except one of them had only one magnet.
The tear down is relatively fast except for one that I had to grind a screw off. Other than that I could do them in 2 minutes each if i get some more torx bits for my drill.
Questions, comments?
