The plan here is to have a number of equipment bays with different types of gear.  I wanted to be able to slide up and down the counter without banging my knees.  The lower shelf is for batteries and power supplies and such..!

Check out the electrical outlets.   All of the 120V outlets are switched.  There is at least one of every kind of 220V socket somewhere on the wall.  There is also a 4 ft. strip under the counter..!
