Do CASE 2 and 3, already have the megaflows in them or are those a crappier brand/version?
Do i need additional fans for better cooling?
Are 200mm fans quieter than two 120s?
My thinking-- if i get the HAF-912 and the additional fans, then the price will come out to close to that of a HAF-922 blue.
The handle, black interior, led switch on/off intrigues me in the Storm Sniper, as well as the overall unique design. But i read that if the fans are replaced in the haf 922 or storm sniper then the LED on/off option wont work anymore.
Thoughts, advice, and comments will be much appreciated.
Hi. I own the HAF 922 (albeit the red version), so I can speak for it in terms of performance and space.
The HAF 922 has a couple of 700 RPM megaflows, with room for another 200mm side fan if you get the model with the grille side panel. It seems that the model you listed is the plexiglass window version. In terms of noise, the 200mm megaflows are deathly silent. You'll only hear them if you put your ear close enough. The included 120mm rear fan is a 1000 RPM one, and it's also silent. Most of the noise would probably come from the GPU and the CPU cooler. Also, the LEDs of the megaflows draw power from the same molex connector as the fan itself, so if you use a fan controller to reduce the fan speed, the LEDs will dim too.
The CM Storm Sniper's front 200mm fan is a more powerful 1000 RPM model. I can't speak for it in terms of acoustics because I haven't heard it in action. Also, the LEDs of the front 200mm fan of the Storm Sniper are driven off a special power connector that comes from the case, which means the LEDs stay bright even if you reduce the fan's output.
All of those cases will fit a 6950. All of them are nice cases: spacious, good airflow, good cable management options, and watercooling ready. However, they are really heavy, especially if you compare them to an aluminum Lian-Li case. But weight is probably of little concern in desktops, since you probably won't be moving them around a lot. The HAF 922 is a nice case, and it's a reasonable upgrade from the 912 since you'll be buying fans anyway. The Storm Sniper is a bit more expensive, but if you can stomach the price, I think it's better than the 922. You might want to get a couple of blue CCFLs and probably a Razer Black Widow Ultimate to complete the blue theme.
