The Sonata IV, built from the ground up for Quiet Computing to continue the legacy of its
predecessors. All of the features in the Sonata IV optimize the case’s quiet design, from the included 620 watt power supply with whisper-quiet 120 mm fan, to the redesigned case airflow that allows for maximum cooling with minimal fans, to the vibration-reducing
silicone grommets for hard drives. Sonata IV is also the most capable Sonata to date, offering a 2.5” drive mount and front-panel USB 3.0. Created to give you a quiet, functional solution for your home, home office or corporate workspace, Sonata IV delivers.
