By the way, the conduit is stiff, but flexible. That way there are no 90 
degree turns, and you can sometimes even push wire through it all the 
way from the rooms to the basement. This is one reason you want the 
central box in the basement, so gravity can help you push cables through.

I have used a electricians fishing tape to pull cable through with no 
problems at all.
