Those caps look as if they didn't get much flux, and knocked-off fairly easy, and clean. Most of The caps in the pics look like they would solder right back on. Most of the components which came loose look re-usable even, although some look like garbage. The boards are pretty beefy, and the solder points are large. I bet a good portion of the PCB's could be fixed with minimal effort, while others are not.
Someone should head up a group buy effort, and hire a bulk repair shop to whip them out. once they see how simple the repairs actually are, it may be worth the effort... just sayin'.
some place like this....      http://sybesmas.com/site/   could make easy work of a stack of those boards
