TBH you probably dont need the 750D, or a 900D for that matter, Unless your doing 100% custom loop with huge-ass radiators, its not really worth it compared to something like the H440

Because your concerned about airflow I'm assuming you are intending on using aircooling for everything.  If that is the case, yes, you want plenty of filtered intakes with little obstruction.  Keep in mind however that you will get more noise with airflow cases typically..... so I would go with the non-airflow version....
