Bently,
Those are some huge "boxes."  (I had to design my last big cabinet in three pieces because my husband was unable to help me.)
I would worry about putting in the LED strip lights because we haven't had great success with longevity of LEDs.  What do you do when they need to be replaced in a couple of years?  Did you make it so they will be easy to change out?
