How to use

Install a Micro ATX or Mini-ITX motherboard inside the chassis, mount the included 350 W power supply and connect power cables to the components. Fit 2.5" or 3.5" storage drives into the appropriate bays and connect them to the motherboard. If additional cooling is required, install an optional 120 mm fan in the front and/or an 80 mm fan in the rear and connect to available fan headers or the power supply.
