Just because it is a low profile case doesn't mean that it’s low on features. In addition to the two drive bays, 1x5.25" and 1x3.5", there are 4 USB 2.0 ports and a pair of audio ports. The power button and indicator LEDs are sequestered in the blue accent stripe so they don't break up the lines of the case.
