yes, exactly! i;m glad that made some sense lol

as for the intake/outtake ratio... yeah i;m not too sure on that one. I've heard some claim that intake should be 1/2 the size of the exhaust, and other say your intake should be 2x the size of the exhaust... so tough call.

Obviously the larger the intake, the less work the exhaust fan has to do, but it will also start taking away from the negative pressure situation.

my box ATM, my intake is probably about 1/2 the size of the exhaust... but this wasn;t by design, it was mostly a matter of convienence. my exhaust had to be somewhat large to accomodate the fan i was using, and the intake I just used like a door knob hole drill bit. I've been meaning to make it a little larger, but i haven;t been having any big temp problems yet... but I know with the summer months coming, i;m going to at least need to double my exhaust and intake.
