SystemLogic has put up a review on the SP USA SilentPC Pro S computer case
The Silent-PC is based on SP´s Pro S mid-tower chassis that operate at, according to SP, noise levels of 21.5 dB(A) without and 24 dB(A) with harddrive access. These values have been confirmed by the ARD, one of Germany´s public TV and radio stations.
