Key Features
- 【Compact and Spacious】Desinged to offer a smaller footprint than most mid tower chassis thanks to its compact design, the TR300 still offers plenty of space to both build and show off components.
- 【Space to Build】Able to accommodate a variety of components at a variety of sizes depending on the build you have planned the TR300 has up to 360mm radiator clearance, 410mm GPU clearance, 260mm PSU clearance, and up to 165mm Air Cooler height.
- 【Keep it Cool】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.
- 【Multi Position PSU Mount】 The TR300 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.
- 【Covered Space】To keep the PSU and extra cables out of sight and out of focus there is a removable front cover that masks the extra cables to shift focus or remove it to present some clean cable management.
