Case PC Jonsbo D31 MESH Midi Tower bianco

The Jonsbo D31 MESH Midi Tower White is a compact PC case designed to balance airflow and clean aesthetics. With a mesh front panel and a white steel chassis, it supports Micro ATX, ITX and DTX motherboards while offering space for standard ATX power supplies. The interior layout accepts a mix of storage drives including one 3.5" bay and two 2.5" bays, and provides mounting for front, top and rear fans to keep components cool.

Advantages

The mesh front and optimized interior allow effective airflow for all common fan configurations, supporting 120mm fans in front and rear, and either 140mm or 120mm fans on top. Its side window gives a clear view of installed components without compromising structural rigidity thanks to a steel frame. The compact footprint (205mm width, 440mm depth, 347.5mm height) makes it suitable for desktop setups where space is limited while still accommodating full-size power supplies and a mix of HDD and SSD storage.

Suitable for

• Compact gaming or productivity builds using Micro ATX, ITX or DTX motherboards
• Systems requiring good case airflow with front mesh intake
• Home or office PCs where a small footprint and a side window are desired

How to use

Install a compatible Micro ATX, ITX or DTX motherboard onto the standoff positions and fit a standard ATX power supply into the PSU bay. Mount storage drives into the dedicated 3.5" and 2.5" bays and route cables through the available openings to maintain airflow. Configure cooling by installing 120mm fans in the front and rear, and a 140mm or 120mm fan on the top if additional exhaust or intake is required. Secure the side panel to complete the build and verify clearances for CPU coolers and graphics cards before powering on the system.

Recommendations

For optimal thermal performance, use the mesh front for intake with at least one front 120mm fan and one rear 120mm exhaust; consider a top 140mm fan for improved hot-air removal. Keep cable routing tidy and use 2.5" SSDs alongside the 3.5" bay for a balanced storage configuration without compromising airflow.
