NZXT Hush
 

Usually the primary criteria when shopping for cases are the exterior design, thermal and acoustic performance and the number of features. A good case usually is a balanced combination of those criteria; a case without fans would be very silent but the thermal performance would be awful, while a case with extremely fast fans would offer extremely good thermal performance but the noise would make it intolerable for many people. With those criteria in mind NZXT designed the Hush, a case which can offer proper cooling and good looks but at the same time be entirely silent and comes at an affordable price. Perhaps one of the most balanced quality cases ever designed? We will soon find out.
