Sell the sticks with the boards, 2 with the BPPC or 1 with each. Most likely the memory modules doesn't fit very well on the B1260, and seeing a picture of a card with rubber bands on can kill some of the hype, because it indicates lazyness (by not finding a module that fits correctly, poorly executed attempt to hold the module in place, etc) If so, I would sell both with the BPPC.
You will get nothing for them if you sell them seperately, as they are easy to find on ebay.
That's my 2 cents.
