Could you make a working, fully functioning tablet from all your parts? It would appear from the list above that you would end up with at least 2 tablets and then a bunch of parts. I think then you could sell those two tablets and only be left with the parts. I know the parts usually go on eBay if you are interested in listing each of them.
You might try UsedHandhelds.com or Gainsaver.com to sell the tablets as well, but they usually require a device to be fully functioning and in good condition before they buy them.
