Previously known as the Sonata Plus, the Sonata Plus 550 is a mid-tower computer case from Antec. Part of the Sonata family, the Sonata Plus 550 is a higher end mainstream offering. Similar to the SOLO and Sonata Designer 500, the Sonata Plus 550 features the same quality case with the addition of a quality modular 550W NeoPower power supply. While not the strongest or quietest power supply, the 550W NeoPower is 80+ certified, meaning it can deliver power efficiently, and at 550W it can provide ample power to even a hungry single card gaming system. Similar to the rest of Antec's lineup, the Sonata Plus 550 comes with a 120mm Antec TriCool fan for those uninterested in purchasing fans separately.
