Accenting the front panel of the TR300 WS is a wooden trim consisting of a series of vertical slants to add some extra style.
Desinged to offer a smaller footprint than most mid tower chassis thanks to its compact design, the TR300 WS still offers plenty of space to both build and show off components.
Able to accommodate a variety of components at a variety of sizes depending on the build you have planned the TR300 WS has up to 360mm radiator clearance, 410mm GPU clearance, 260mm PSU clearance, and up to 165mm Air Cooler height.
Capable of fitting up to eight 120mm fans, with space for three 120mm fans at the top and bottom of the chassis and room for another fan at both the front and back of the chassis, and to start things off there is a 120mm PWM fan preinstalled on the rear mount.
The TR300 WS features a front mounted PSU with a four position bracket to allow for different mounting heights to make room for either larger graphics cards or more fans and radiators at the top for a balanced space.
