How to use

Install an ITX motherboard and, if required, fit a single 3.5" or 2.5" drive in the internal bay. Mount expansion cards into the dual-PCI slots and route any serial connectors through the six DB9/DB15 rear cutouts; use the dedicated rear cutout for a dual-USB module if needed. Connect power supply (not included) according to the motherboard and drive requirements, and ensure the 80 mm front fan is connected for proper cooling. Align the perforated slot bracket for optimal ventilation and secure all panels before operation.

Recommendations

For reliable long-term operation, use a compatible low-profile power supply, avoid blocking the front fan intake, and choose components sized for ITX layouts. If multiple serial devices are required, verify connector pinouts before installation to prevent mismatches.
