How to use

Install the motherboard according to its form factor standoffs and secure it to the chassis. Mount storage drives into the dedicated 3.5" or 2.5" bays using the provided brackets or trays. Connect the pre-installed 120 mm front fan to a motherboard fan header or fan hub, and add additional 120 mm or 140 mm fans as needed to optimize airflow. Route power supply and data cables through the case routing channels to maintain unobstructed airflow. Verify front I/O connections for the two USB 3.2 Gen 1 Type-A ports and connect case power and reset switches to the motherboard headers.

Recommendations

For balanced cooling performance, configure a front intake fan setup using the pre-installed 120 mm fan and add one or two additional 120 mm or 140 mm fans to increase positive airflow. Use the available 2.5" bays for SSDs to improve storage performance and place heavier 3.5" drives in the dedicated bays. Maintain clear airflow paths by managing cables behind the motherboard tray and ensure the power supply intake is unobstructed.
