How to use

Install a compatible motherboard (Mini-ITX, Micro ATX, ATX or EATX) following the standoffs and I/O alignment, mount storage drives into the dedicated 2.5" or 3.5" bays, and connect the preinstalled fans to the motherboard fan headers or a fan controller. Install the power supply in the designated compartment and route cables through the case cutouts for optimal airflow and neat cable management. Verify front-panel connectors are connected to the motherboard header before powering on.

Recommendations

For reliable cooling performance, use the case's preinstalled front 140 mm fans in combination with the rear fan and keep dust filters clean. When installing high-profile CPU coolers or long graphics cards, check component clearance against the case dimensions. Use 2.5" SSDs for faster system drives and 3.5" HDDs for larger mass storage.
