I have a coolermaster HAF 932 and it's quite loud even when it's just idling. Realistically, 99% of the time, my pc isn't doing anything intense so I feel like I'm wasting the cooling potential of the case and putting up with a lot of noise for nothing. Skype calls all pick up the loud droning even though I've set up my mic to mitigate it. Cases like the Fractal Design Define R4 or Nanoxia Deep Silence 1 are supposed to be quiet, but how much quieter are they really? I have 4 hard drives, an evga GTX770 with ACX cooler, a titan fenrir, and a corsair psu, so all of those things will be making noise, and then there are the case fans. I find it hard to believe that a new case will really make a huge difference; is it worth it?
