Personally, I'd set it up as 1 rear exhaust (at lower rpm), 2 top exhaust on kraken x52 (fan set up at lower rpm), and 2 in front intake (at higher rpm), all just using 5 fans for "positive" airflow cfm.
However, in your case, if you really want the AIO in front. It would simply be 1 rear exhaust (at lower rpm), 3 top exhaust (at slowest rpm possible), and 2 front intake on kraken x52 (fan set up at higher rpm). Depending on the actual fans you used and its rpm-to-cfm rate, I'd still compute the intakes to have higher cfm's than the total of all exhausts for positive airflow.
