For those looking for a massive airflow ripping through your case, take a look at Virtual Hideout. They have a review up of the Chenbro Genie Case and it pushes almost 350CFM of air! here's a snip:
"it's a brand-name top quality case. what's all this mean? it's means that unless you're prepared to spend hours upon hours trying to dremel (or whatever) all these mods yourself, be prepared to pay about $435 for this exact setup. That does include everything you see as far as the exact mods and the Enermax 431 included. Is that alot of money? Hell yea it is! But, the most important question is : "Is it too much money for this case?" And in that I say "NO!" You will receive a very detailed invoice with this case breaking down every single mod or included accessory and it's cost to you. There is no hidden costs. that's one of the best, and most professional, things that Coolcases.com includes with all its cases."
