"Generally, cases with a power supply are intended for the budget market. I believe Antec had this in mind with the Antec Sonata III Case. This product is mostly steel with a stylish plastic front bezel. There are 3x5.25", 2x3.5" (ext), and 4x3.5" (int) drive bays. Conveniently located at the front are 2 USB2 ports, eSATA port, a microphone jack and headphone jack. There is one included Antec Tricoool 120mm fan at the back and an optional 120mm fan can be installed at the front. Overall, this is a great case and they include an excellent high efficiency 500W power supply. Watch the video to find out more and check out the bloopers at the end." ~3dGameMan.com
