Antec have today expanded their popular Sonata line of mid-tower cases with the all new Sonata III. Once again with silence in mind, at first glance this new version retains the characteristics of its predecessors though there are quite a number of subtle changes throughout.

For one, there's now a series of USB, eSATA and audio ports positioned horizontally at the front of the case on the spiffy new bezel design. But more importantly, inside the case Antec have chosen to stick with their 120mm TriCool exhaust fan (which allows you to manually choose from three speed settings), some new vents added for better air circulation and of course the four sideways-mounted hard drive trays with silicone grommets are still there too. Then there's the PSU, thats been moved up from the 450 SmartPower 2.0 model on the Sonata II series to an EarthWatts series EA 500W unit.

Building on the original's features, Sonata III's internal drive bay trays are now fitted with soft silicone grommets to reduce and absorb hard drive vibrations. The cooling system, with one rear 120mm TriCool(TM) fan and an optional front-mount for a 120mm case fan, allows users to balance quiet computing with the precise cooling their system needs. And attractive new chassis vents make for improved circulation, channeling cool air silently throughout the case. Sonata III is also fitted with a built-in washable air filter to control dust build and keep internal temperatures down.
