Cooler Guys have been making the Windtunnel model of cases for a while now, and each seems to get progressively better than the last. Can the newest model keep up the reputation? The only way to fond out is to head on over to WinHQ.net and check out their review of the Windtunnel IV Case. here's a snip:

"After our excellent experience with the Windtunnel II Gamers case, I thought that CoolerGuys couldn't get any better cooling-wise since the case performed so well. Now that the new Wintunnel III and IV are out, we may see even better cooling at a less expensive price. Today we look at the newest case, the Windtunnel IV."
