Thanks Barb. I was originally going to rabbet the sides to the top/bottom, but feared just what you are sharing. Now the plan is to butt join the sides on top of the bottom/floor with screws and glue. While I figure the back of the table will be protected from racking by the full-piece back wall, I am wondering about the front of the cabinet.

I am considering adding 2in wide vertical separators (facing) on both front sides and the two inner ones as well. My thoughts are that while I will lose some drawer/storage space, the 2in facing should help prevent some of the racking involved every time the loaded cabinet is moved. Is 2in enough on the corners? Maybe 3in wide, corners only, but inner facing still 2in?

I have not even thought about designing the drawers yet, so I am open to suggestions regarding the above.
