I did the same thing twenty years ago, when my house was built. I ran 2 CAT5 and 2 RG6 to every corner of every room. Some areas got more. For example the garage has 12 CAT5 feeds distributed between three walls. Everything goes to a standard 19 inch EIA rack in the garage and is terminated and labelled on patch panels.

Rather than bring out the connections in each room, I use a toner to find the feeds and only bring out what I need when I need it.
