## Long description

The Jonsbo D31 STD Midi Tower White is a compact PC case designed for Micro ATX, ITX and DTX builds. Its white steel chassis combines a small footprint with practical internal space, featuring a front power supply location that supports ATX power supplies. The case includes a side window for component visibility and supports multiple cooling configurations, including up to three 120mm front fans, one 120mm rear fan and optional 140mm top fans. Drive support covers both 2.5" SSD form factor and 2.5"/3.5" HDD installations, making the D31 STD suitable for a range of storage setups within a lightweight 5.9 kg enclosure.
Advantages
The case offers a balance of compact dimensions (205mm width, 440mm depth, 347.5mm height) and airflow options, allowing for effective cooling in a small chassis. Steel construction provides structural rigidity while keeping the weight moderate. The front power supply placement supports standard ATX PSUs without sacrificing internal layout simplicity. A side window allows visual access to internal components for diagnostics or aesthetic setups.
Suitable for
 Compact Micro ATX or ITX gaming and productivity builds
 Home or office systems where space-saving is important
 Builds requiring multiple 2.5" SSDs and at least one 3.5" HDD
 Systems that need a visible interior via side window

How to use
Install a compatible Micro ATX, ITX or DTX motherboard on the internal mounting points and mount an ATX power supply in the front compartment.

Fit cooling fans according to the supported positions—up to three 120mm at the front, one 120mm at the rear and optional 140mm on top—to establish airflow from front to rear and through the top exhaust. Route cables behind the motherboard tray and secure them to maintain unobstructed airflow through the case.
Usage recommendations
For balanced thermal performance in this compact chassis, use at least one front intake fan and the rear exhaust fan. Choose low-profile CPU coolers or compact GPU models if space constraints arise, and consider using 2.5" SSDs for primary storage to simplify internal cable management. Regularly clean dust filters and maintain front-to-rear airflow to preserve component longevity.
