Quiet - Peaceful - Silent... Serenity. The Puget Systems Serenity Pro proves that high-performance computers can still be whisper-quiet. Intel’s high-efficiency Ivy Bridge processors provide the platform for all Serenity systems, but this Pro variant offers higher-performance video cards and hard drives - at the cost of a little added noise. We use the already-quiet Antec P183 case for this, as in the even quieter Serenity SPCR, but many of the modifications we developed to silence that type of system can optionally be applied here as well. The exact noise level will depend on the specific hardware selected, but the configuration options are still limited to avoid any specifically loud components. If you want great performance combined with very quiet operation, look no further.
