Product information

Description

The Jonsbo D31 STD Midi Tower Black is a compact PC case designed for Micro ATX, ITX and DTX systems. With external dimensions of 205mm (W) x 440mm (D) x 347.5mm (H) and a steel construction, the chassis provides a balance of rigidity and space efficiency. The case supports ATX power supplies and offers multiple mounting locations for cooling fans, including front and top 120mm positions and bottom mounts that accept 140mm or 120mm fans. Storage options include one 3.5" bay and two 2.5" bays, while a side window allows visual access to internal components.

Advantages

The Jonsbo D31 STD combines a compact footprint with flexible cooling and storage options. Steel construction ensures structural durability and the side window provides component visibility without significantly increasing external dimensions. Support for ATX power supplies and multiple fan mounting points allows straightforward installation of common components and aftermarket cooling. The case’s layout is suitable for efficient airflow in smaller builds.

Suitable for

Compact Micro ATX or ITX gaming builds
Home office or multimedia PCs with limited desk space
Silent or air-cooled systems using 120mm/140mm fans
Systems requiring a single 3.5" drive plus SSD storage

Key specifications

Material: Steel
External dimensions (W x D x H): 205mm x 440mm x 347.5mm
Weight: 6.5 kg

How to use

Install a compatible Micro ATX, ITX or DTX motherboard on the provided standoffs and mount an ATX power supply at the designated position. Fit the storage drives into the 3.5" and 2.5" bays using the drive brackets or screw mounts supplied with the case. Configure cooling by installing 120mm fans in the front and top positions and optionally a 140mm or 120mm fan at the bottom to promote airflow. Route cables along the chassis edges to maintain unobstructed airflow and secure panels after component installation.

Usage recommendations

For optimal thermal performance, use a front intake 120mm fan combined with a top exhaust 120mm fan and, if space allows, a bottom 120mm or 140mm intake. Choose low-profile CPU coolers or compact air coolers compatible with the case’s internal clearance, and prefer 2.5" SSDs for the fastest storage response in small builds.
