If it is working for you then that is great. I have had many people over the years bring their cars to me where they tried to build their boxes with just wood glue and every one sounded awful, leaked, and or fell apart, wanting it rebuilt. Like I said I would never recommend it, but if it is working for you then . Plus even for it to work it would take a shop with a very experienced woodworker with the tools for perfect joints, which most have neither. Also proper box for a W7 should have thicker walls than normal and internal bracing.
