Well, it would be similar to your current setup i would imagine. what is your current body_wrapper width? If its 1000px most smaller monitors will show a horizonal scroll if you are not using overflow:hidden;

you could always make it fluid

body_wrapper width:100%

other elements 80% with a min-width of 650px or something. and the top bar being 100%

you should also set a max-width of like 1000px on the 'other elements' as people with larger monitors, it is annoying to read posts that stretch too far.
