Dennis,
This is what I had in mind
All 3/4" MDF, all support will be bearing on the two sides and back panels. A full sheet will be on the top to help distribute the load (attached with clips), and a shelf at the bottom. all panels will be glued & screwed. I do not have access to a biscuit tool...maybe I should get one.
Here is a Drawing
Thanks for the info and the help
