Antec has just extended its popular Sonata line of Quiet Computing cases with the new Sonata Proto which is based around their best-selling Sonata III 500 chassis with a few tweaks and adjustments.

The Sonato Proto has clean lines and styling, using a smart looking matte black exterior. Interally it gives a good range of features, especially for its MSRP of $74.95.

Antec knows how many people are turning to 2.5-inch SSDs as their primary drive for operating system use and as such, they provide a mount for 2.5-inch drives.

There is room for three 5.25" devices and two 3.5" devices accessible externally, along with the aforementioned 2.5" bay and four 3.5" HDD bays inside for SSD/HDD mounting.

At the rear of the chassis there is a 120mm TwoCool (2-speed) fan. There are also seven expansion slots available at the rear for add-in cards.

Antec has already begun shipping the Sonata Proto to major distributers/retailers/e-tailers with the aforementioned MSRP of $74.95.
