I know you have seen my "Man Cave" before Scott. Not much has changed other that adding a couple more cabinets. Add as many lights as you can. Put some on the walls maybe up high to help with less shadows. Also my color of choice is white for the walls. Gives more light and is great for painting your favorite website logo on the wall. Would really jumps out at ya with blue on white.
Here is a site that has a million ideas. Sign up and you can surf for days. Be sure to add extra electrical and air lines if need.
