Airflow question

[kleox64]

Ive mentioned this in another thread but it will make more sense here, if I have X airflow into a case doesnt the exhaust have to be more or less the same?

Iam not into the negative/positive airflow debate, the best way I think is to have more or less even airflow.

Everything that goes in must come out, it's just a matter of which gets the emphasis, push, pull, or neither.
