Can these be used to store computer boards in?

Not these you are going to need a larger size.

Are these metal in or metal out? Thanks.

I cannot tell from visual inspection, but if I had to guess, it appears to have a more metallic look on the inside. Out of curiosity, I placed ohmmeter probes close together on both the inside and outside. Both showed infinite resistance, however I was not sure this would show anything. If there is metal, maybe it is imbedded in the mylar. However, visually they look about the same as more expensive name brand ones that I have ordered from traditional electronic suppliers.

Are these electronic static discharge bags considered to be a real farayday cage?

These bags are pretty nice anti static bags, but i do not believe they are Radio Frequency shielding. I would not trust them to stop radio waves,
