The 4 x 4 dream is dead. I started tearing apart the office yesterday afternoon and evening and mocking up a 4 x 4 install. I would need to shorten the ceiling fan blades by 4" and it would completely destroy the flow of my office. Not to mention the aesthetics. Not that there is much to look at. But as a office/cave it ain't bad for a man. And the wife even enjoys being in here at times. She does like a man vibe atmosphere. She helped with the mockup and tearing stuff apart. And we both looked at each other and knew what would be lost wouldn't be worth the gain. As much as I dislike the 3 x 3 it does fit properly. We spent hours measuring, moving stuff around, laying it out and playing with options on the computer. In the end 6" killed the dream.
