Carcasa de PC Jonsbo D31 MESH Midi Tower Negra

The Jonsbo D31 MESH Midi Tower Black is a compact PC case designed to combine a minimalist exterior with effective ventilation. Its mesh front and top layout facilitates airflow while the internal arrangement supports small to mid-size systems. The case accepts Micro ATX, ITX and DTX motherboards and includes mounting for both 2.5" and 3.5" drives. With external dimensions of 205mm (W) x 440mm (D) x 347.5mm (H) and a durable steel construction, it balances a small footprint and structural rigidity for home or office builds.

Advantages

The steel chassis and mesh panels provide sturdiness and improved air intake for active cooling. Support for multiple fan placements — up to three 120mm or 140mm fans on the top — enables configurable airflow paths. A front-mounted power supply position simplifies cable routing and system assembly. The case includes a side window that allows component visibility without increasing overall size, and the relatively low weight makes it easier to handle during installation.

Suitable for

• Compact gaming or productivity builds using Micro ATX, ITX or DTX motherboards
• Systems requiring multiple 2.5" SSDs and a single 3.5" HDD
• Users prioritizing improved airflow through mesh panels and top fan support
• Home or office PCs where a small footprint and accessible front power supply are preferred

How to use

Install a compatible Micro ATX, ITX or DTX motherboard on the provided standoffs, then mount storage drives into the designated 2.5" and 3.5" bays. Place the power supply in the front-mounted position and route cables toward the motherboard and components, using available openings to keep cables tidy. Fit fans in the top locations as needed for intake or exhaust depending on your cooling strategy, and secure the side panel to complete assembly. The mesh panels should remain unobstructed for effective airflow.

Recommendations

For optimal thermal performance, use at least two case fans with one configured to draw air in and one to exhaust; maintain clear airflow paths by arranging cables behind the motherboard tray where possible. Choose 2.5" SSDs for primary storage and the 3.5" bay for larger mass-storage drives to balance speed and capacity.
