There's a company that makes mounts for putting cable boxes behind wall mounted TVs. There are probably other companies with this sort of product too. I don't know if that would work for your setup or not.
I don't know if it's possible to route the wires through the wall to a better/less visible area.
There are some gun safe hidden compartment mantles people will make for you. Google brings up a few. Could also DIY it if you're handy.
Otherwise you could hide it in something decorative like fake books or a box or behind a picture or something.
