Cooling? The Case isn't responsible for Cooling.
It may provide a Airflow but the Real Cooling is with the Dedicated Coolers.
Get whichever you like.
You'll get a Good Cooling when you'll apply 5-6 fans. Not much, but around 3-4 C.
Case is all about Looks (Thats my Opinion)
You should have good Lighting and some Awesome Mods. :lol:
