How to use
Install the compatible motherboard (ATX, Micro-ATX or Mini-ITX) on the standoffs, mount the power supply in the designated bay and secure drives in the 3.5" or 2.5" trays. Fit the graphics card (up to 350 mm) in the PCIe slots and install a CPU cooler that fits the available height. Connect the included Stratus 120 PWM ARGB fans to appropriate headers or a controller and route cables to maintain unobstructed airflow. If you plan to use a front radiator, confirm clearance for the chosen radiator thickness and fan configuration before final assembly.
Usage recommendations
For balanced noise and cooling performance, use the PWM fan headers to set a curve that increases fan speed under higher CPU/GPU load. When installing multiple drives or a 360 mm radiator, plan cable routing and component placement to avoid blocking front airflow and ensure optimal intake through the front fan mounts.
