Built with a strong "shield" concept at heart, the BUC's core is echoed across its front panel design, in strong SECC steel construction and a hard-wearing and stylish black interior and exterior. With the clever EZ-swap HDD drive bay and a lockable door, it allows access to three HDD without having to remove the whole side panel, while the tool-less, vibration reducing drive bays complete the package to yield a triple innovation from In-Win. The convenient Super-speed USB 3.0, USB 2.0, audio and eSATA ports on the top of the chassis allows users to easily connect headsets, cameras, cell phones, external hard drives and a wealth of other devices with ease. Finally, two integrated 120mm and several extra fan positions give it excellent cooling potential for all the latest performance hardware as well. With core design innovations, support for the latest PC hardware and a high quality of construction, the In-Win BUC PC chassis is a great choice for PC builders worldwide.
