<snip>Almost forgot, to those of you worried about the use of the plastic on the side panels which doesn't absorb sound versus acoustic foam, it's just a different way of doing it. One of the ways to prevent/tame sounds resonance is to increase the mass of the object resonating, which this will do. Acoustic foam would work well though too, as it will absorb some of the sound, so I guess it's all in what you folks prefer. Hope this helps!!
Interesting, in a PC case, reducing sound transmission (preventing the noise to come OUT of the case) is more important than sound absortion. And yeah, mass is the most important factor in that department.
Ok seems like I have a 2012 case upgrade coming
