unless using something like Silverstone AP fans, airflow in a case is always very turbulent... there is actually nothing to be gained by using APs or by "laminar" airflow. "laminar" Airflow is overrated. Balance counts: slight more IN than out without "fighting"
As long as you dont have your fans "fighting" too much, its ok
A setup like 2 front intake & 1 rear out + 1 top out should be enough. Depends a bit on the HS you'll use on the CPU
if you want positive pressure: 2 front intake, 2 top intake, 1 rear out - but you might have to run the rear out a bit faster thou
I dont see why you would need a bottom intake fan honestly; but, it depends on the your components: the HS on the CPU - because orientation of that HS might dictate how you have to set up the top & rear fan.
And the GPU, if a reference design, that exhausts to the the rear, then it MIGHT help to have bottom fan. IF one of those MSI Frozen series.. they tend to dump a lot of warm air IN the case and then Top intake + higher CFM rear fan might be needed
Anyways, if you think you have the need to for lots of fans at 1000 cfm, then this is not the case for you... then you need something different,with more ventilation options.
