Are you talking existing cabinet? If not, I have a new 65413 Mitsubishi, and the lower panel comes off leaving the screen sticking out about 1 inch or so from the base. This allows you to mount the TV so that only the screen is visible. I don't know if anyone makes a cabinet specifically for this TV, but one could be custom built.
The lower half of the TV contains the optics and must be present for the TV to work.
