K380 is an entry level mid-tower with a rugged look and full matte black finish. Up to four fans can be installed. One 120mm red LED fan located behind the front panel is included and offers optimized cooling. A fan can be mounted on the windowed side panel to keep graphics cards cool. Large high-end graphics cards, like the NVIDIA GTX690 and AMD HD 7990, are supported thanks to K380's spacious interior. It comes with three tool-less 5.25" bays and space for seven HDDs (three tool-less) to increase expandability. An USB 3.0 port lets you charge and access data on smart phones and tablets much faster than USB 2.0.
