Unfortunately, that's the risk one takes when buying something that's
obviously been resealed and inspected by the dealer, rather than
having the same thing done by the manufacturer, who presumably will
retest the product and make sure the nothing is missing. Also, I
can't realy blame Fry's for the board swap, as they were as much the
victim as I was.

If Fry's was a victim, it was its own victim. Any business that doesn't
carefully check returned items deserves what it gets. Unfortunately, what
they got was passed on to you.
