Should I use static pressure fans or air flow fans in the Silent Base 800?

To preference this: I am aware the static pressure fans are great for radiators and restricted areas. Air flow fans are for open spaces. 

 

So i'm planning my next build, and it will be silent. I've chosen the Be quiet! Silent Base 800. Obviously in the front you need static pressure fans, because it's very restricted. In the top and bottom it has plastic cowls/covers. Seen here, here, here, and here. So which is best for There is maybe 1 inch/2.5cm space between, and only two slits on the top to let air through. There's a similar situation on the bottom with just vents on the back side. So my question is, which fans are best for this situation? SP or AF? Or a combo fans like the NF-P12? 

 

I'm also thinking of mounting a Noctua NH-D15 vertically so the hot exhaust get's vented out the top, and mounting 2 140mm's on the top as outtakes, and one 120mm in the back as intake. (Similar to Linus' silent build). 

 

Thanks for the help!

Go with the new NF-P12, I have a mixture of SP and AF fans in multiple builds, have changed them around and my temps are always the same. Try to keep the pressure positive though.

Alright, i'll go with NF-P12s for the 120mm's. But for the 140mm would a NF-P14s PWM Redux or a NF-A14 PWM be better?

 

I plan to have 4 intake fans, and 2 exhaust, I think that will achieve positive pressure.

It definitely will result in positive pressure, unless the intake fans were to have drastically lower flow rates than the exhaust fans.
