I think the largest problem with Racing Cabs is they fact that you need to make them fit through a standard house door and/or basement door.  I made the GameCab Driver at 30 Inches in width and it will not fit into the front door of my house.  To be truthfull, it's really going to be a tight sqeeze making it into the outside basement door of my house.  Once the Cabinet finally reaches my basement I will need to totaly remove the door frame and about 3 inches of sheetrock in my gameroom just to bring it to it final resting place.
Could you imagine what I would have to go through in order to bring a cockpit cabinet into the Gameroom....
In order to combat this minor problem I'm going to release the final plans with a the 30 inch and 25.5 inch designs.  I picked 30 inches because I plan on adding in some lights, gauges and a really nice Knight Rider effect.
Just use the above as words of caution to the people who like to get crazy when building (Like Me).  It's fun to make a killer cabinet but you need to check the door size first
