Since you can hear/see the Cosmic Background Radiation left over from the Big Bang on your tv/radio as static, would putting it inside a Faraday Cage block out the static?

This is an interesting question.  Let's suppose that we're deep in space so that there's no other sources of electromagnetic radiation -- we're just dealing with the CMB.  Furthermore, let's suppose that our Faraday cage is perfect -- it's made out of a perfect conductor and it has no holes in it.  If we put a receiver inside, we will find that yes, indeed, the Faraday cage blocks out the static. 

Now, in reality, the conductor will not be perfect.  The motions of the electrons in the conductor will generate heat and will eventually warm up the Faraday cage to the same temperature as the CMB -- 2.7 K (let's assume that we started out close to absolute zero).  Once this happens, the Faraday cage itself will begin to radiate as a blackbody at 2.7 K, and so it will produce exactly the same radiation signature as the CMB itself.  So although the Faraday cage would work temporarily, it would not be a permanent solution.
