How to use
Install the motherboard on the pre-punched standoffs and route power and data cables through the provided cable holes and the 27 mm cable channel. Mount storage drives in the dedicated 3.5" or 2.5" bays and install the GPU, noting the generous clearance for long cards; optionally use a vertical GPU mount (sold separately) after removing the seven PCIe slot covers. Fit AIO radiators at the front or top up to 360 mm, and confirm fan orientation to maintain front-to-back airflow. Use the quick-release dust filters for regular cleaning.
Usage recommendations
For best thermal results, maintain a front-to-back airflow configuration, keep the dust filters clean, and choose PWM-controlled fans or a compatible fan hub to optimize noise versus cooling performance. When installing very wide GPUs, verify clearance with installed cables and cooling solutions.
