I'm building a prototype electronic device and need to construct a
case for the prototype. The approximated dimensions are 13" x 19" x
3", and it needs to have cooling slots in the bottom for fan driven
airflow.

I'd like as light-weight, but strong material as possible.

My one thought was to recycle PET soda bottles and develop a home-made
pour/compression mold, but I'm not certain that's the practical way.

Or, perhaps using a pourable resin (polyester or epoxy?)

You want Sylgard, a pourable silicone resin, comes clear and can be used
to encase electronics. The only problem with it is it helps to degass it
after you mix in the activator, you can rig up decent vacuum with
Vernouli type device attached to a tap. It is very thermally resistant
and has excellent shock absorption properties. Might not be good for
airflow though.
