If your going to build any drawer system under that bench consider making it so the very top is an open topped drawer that you pull out.This will be real handy for plans & to clear the top of the bench when you need to make the one cut or rip that you forgot to make before you started using the off-feed table for a bench. DAMHINT I wish mine was this way every time. Also make the cabinet in sections that screw together. I don't need to tell you the why of this we both have small shops. 2 small sections screwed together with drawers or shelves with the outside ends 3" - 4" taller then the actual case will make a place to fasten glides for the top drawer for plans & miscellaneous items as you clear the bench top to saw.
