Product information

Description

The Jonsbo D31 STD Midi Tower Black is a compact steel PC case engineered for conventional desktop builds where airflow, component compatibility and a clean aesthetic are required. With support for Micro ATX, ITX and DTX motherboards, a side window and dedicated mounting for both 2.5" and 3.5" drives, this case balances internal space and external footprint. Its dimensions (205 mm width, 440 mm depth, 347.5 mm height) make it suitable for smaller desks while still accommodating standard ATX power supplies and multiple cooling fan configurations.

Advantages

The steel construction provides structural rigidity and long-term durability while keeping weight moderate at 6.5 kg. Multiple fan mounting options (front, top and bottom) allow for flexible airflow setups, including support for 120 mm front and top fans and 120 mm or 140 mm bottom fans. The inclusion of a side window enables component visibility without sacrificing usable interior space, and the case offers dedicated bays for both 2.5" SSDs and 3.5" HDDs to suit mixed storage configurations.

Suitable for

  • Home or office Micro ATX and ITX desktop builds
  • Compact gaming systems with discrete GPU
  • Home lab or network-attached builds that require 2.5" and 3.5" drives
  • Upgrades where standard ATX power supply compatibility is needed

Key specifications

  • Form factor: Midi Tower
  • Supported motherboard sizes: Micro ATX, ITX, DTX
  • Dimensions: 205 mm (W) x 440 mm (D) x 347.5 mm (H)
  • Material: Steel
  • Product colour: Black
  • Weight: 6.5 kg
  • Drive bays: 1 × 3.5" bay, 2 × 2.5" bays
  • Cooling support: 120 mm front and top fans; 120 mm or 140 mm bottom fan options
  • Side panel: windowed
  • Power supply: supports standard ATX PSU

How to use

Install a compatible Micro ATX, ITX or DTX motherboard on the provided mounting points, secure a standard ATX power supply in the PSU area, and mount storage drives into the dedicated 2.5" and 3.5" bays. Use the available fan mounting positions to configure airflow: front and top for intake or exhaust with 120 mm fans and bottom for optional intake or exhaust with a 120 mm or 140 mm fan. Route cables behind the motherboard tray where space allows and secure them to avoid airflow obstruction. Ensure the side window panel is properly fastened after assembly.

Usage recommendations

For balanced thermal performance, place an intake fan at the front and an exhaust fan at the top. When using a bottom fan, verify clearance for a 140 mm unit if planning larger fans. Use 2.5" SSDs for operating system and frequently accessed files and 3.5" HDD for bulk storage. Regularly clean dust filters and internal surfaces to maintain unobstructed airflow and stable component temperatures.
