Noise reduction for MasterBox 5? in Masterbox 5 Series Posted May 6, 2017 Hi. I have a computer with a MasterBox 5 case that I (gasp!) did not build myself. I don't have any beefs with the case, and it's not very noisy, but I am very noise-sensitive, and it's not actually the King of Quiet. Does CM have case-specific baffles, etc. to quiet things down, or do I really need to get a quiet-focused case like the Silencio line? Thanks.
