Probably not immersible, but NEMA 12 cabinets (expensive, gasketed door,
welded seams) and convection cooling is the way they do harsh
environment computing gear. You'd also need a heater inside if you want
to make the thing operate at much below freezing. Those cabinets are
also oil and gas tight, but there's a higher NEMA rating for explosion
proof/airport baggage handler proof. 8^)

You could do the same by putting one of the Paragons into a NEMA 12 box
with a rack mount built in, and using gas/liquid tight connections as
needed. A small internal fan, or thermally conductive block from the
finals to an external heat sink (also gasketed, since the cabinets tend
to be steel) would not be a bad idea. Hmmm...
