I'm building a new powerhouse soon, but i don't know which case to build it in! I want a case with the best airflow I can get and I would be glad if it is silent too.. it's a gaming rig and a render pc. I have some suggestions here.. my max price is 150 USD.
And what which fans is the most important fans in a case?
Cooler Master HAF 922 Black
Zalman Z11 Plus Black
Fractal Design Define R4
Cooler Master HAF XM
Nzxt Phantom 410 Black
Nzxt Hades Mid Tower Black
Cooler Master Storm Enforcer
Zalman Z9 U3
Thermaltake Overseer RX-I Black
Corsair Vengeance C70
BitFenix Colossus Mid tower White
If you want good airflow, the coolermaster HAF cases are designed specifically for High Air Flow (HAF) hence the name. If you want quiet, look for cases that take larger fans such as 200mm (again seen with HAF cases) whcih run quieter, slower and push greater amounts of air.
I don't actually know all the cases you've listed, but the HAF XM has 2 or 3 200mm fans. Phantom 410 looks good (has a front door access to drives which I personalyl don't like ) and lots of fans - none large though.
It all does come down to personal opinion mostly.
Hope some of this helps
