Another big change for the Sonata III is the power supply. Antec includes their award winning Earthwatts 500, a very quiet and well built 500 watt power supply.  You can check out our review of the Earthwatts power supply here.

     The Earthwatts 500 has plenty of power connectors which include 2 PCI-E and 4 SATA connectors. This is definitely one of the best power supplies I've seen included in a computer case.

     The Sonata III has four very nice slide out hard drive trays. The trays also have rubber dampeners that help absorb hard drive vibration.

     Here we see just how easy it is to access the hard drives and hard drive trays. The trays are solidly built and firmly held in place.

     Internally, the Sonata III is actually quite simple. However, sometimes simplicity is what makes a good product great, which is the case here.

Conclusion:

     The Sonata III is Antec's best "Quiet Computing" case yet. The case has great looks and exceptional quality. Even though the case is fairly simple, it still has some excellent features that work extremely well. The case is well vented, but nearly silent with the variable speed cooling fan and Earthwatts PSU. Speaking of PSU, Antec has spared no expense by going with the Earthwatts series. With a good quality power supply, this case is very appealing to system builders of all types. Normally I would say a case of this type is a "good starter case", however the quality build and features of this case place the Sonata III firmly in the mid level class and may even appeal to the enthusiast crowd. As for price, this case can be snatched up for about $150. At first glance this price may appear to be a little high until you read the fine print which states there is a 500w Earthwatts power supply included! Very nice case Antec...
