Post a drawing of what you asking and I will measure it for you.

Keep the internal dimensions the same.

Don't know where you dwell or the conditions but you might to consider using marine grade - less likely to 'fall apart' when the humidity is high.

MDF is heavy! I built a mini-platforms [with casters] for when I had to move my LH transmission line speakers.
Plywood is both stiffer and lighter than mdf, but not as damp, ply is by far the prefered sub and pa material. 5 ply is stiffer and cheaper than many-ply baltic, but can have voids. I recently built with half inch ply with great results, braced properly.
