Product information

Description

The Inter-Tech IPC S31B is a compact, cost-efficient server-style computer case designed for Mini Server systems and ITX motherboards. Constructed from durable materials with precise workmanship, the case provides space for one 3.5" or 2.5" drive, an 80 mm front fan, and a dual-PCI slot layout with multiple rear cutouts for serial and USB connectors.

Advantages

The case combines a small footprint (270 mm × 230 mm × 167 mm) with support for ITX motherboards and a dual-PCI slot configuration. It includes six cutouts suitable for DB9/DB15 ports and one cutout for a dual-USB port at the rear, an 80 mm front fan for airflow, a perforated slot bracket, and two front USB 2.0 ports. The unit is lightweight (approx. 2.965–3.71 kg depending on configuration) and offers a reliable enclosure for server or compact workstation builds.

Suitable for

Compact mini server builds with ITX motherboards
Small office or home server installations
Embedded systems requiring serial DB9/DB15 connectivity
Projects needing a dual-PCI slot and front USB 2.0 access

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.

Usage 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.
