My question is due to us getting bombarded every 2 days now with CME's coming from the sun, the next one scheduled to hit earth tomorrow is that something I could be using for promotional stuff?
You would just make a fool of yourself. Most computer cases are actual faraday cages, if properly grounded (and within there are plenty more, hdds for instance). Not to protect against external radiation but to shield you against EM emission from within the case.
Now "cosmic bombardment". Those very fast protons hit our atmosphere (causing nice looking aurorae) and decay mostly to muons at ground level. Bad news, there is no reasonable way to avoid them. Even if you put your safe deep beyond a mountain, they will get ya.
