The size of the exhaust hole is not as important as the fan fitted to it- Try to get exhaust fans with CFM ratings equal to your blower. That way you have a nice, constant flow thru your case. Uneven intake\exhaust levels can develop static pressure in your case that mess up air flow. Experiment to find what is best for you.
