I agree. Especially the ones heated high enough for the melted plastic
or scorch damage. A radiative and convective heat soak is pretty damaging.
Consider the flow temperature of the materials inside. Unless the fire
was flash fire, the entire thing would have been heated for some amount
of time (15 minutes minimum usually, to 45 minutes) due to response time
of the equipment.
Not evident in the photos would be possible contamination from either
fire suppressant materials or water to extinguish the blaze.
Like I said, Ethan is looking for a cabinet for an 11/70 stripped out of
such, and these probably are okay for that. Maybe some of the other
bits after inspectiong, but I'd not trust the boards up front. It would
be a project I'd want a solid shop of parts to do testing for every
board involved to certify they work.
Most people I know have one system in their basement, lab or garage, and
I'd personally not want to put boards from a source like this into such,
unless i had nothing to lose.
