Caixa de PC Jonsbo U4 Mini Mini Tower Preto

The Jonsbo U4 Mini Mini Tower Black is a compact PC case designed for space-saving desktop builds while maintaining effective airflow. It supports standard ATX power supplies, accepts both 3.5" HDD and 2.5" SSD drives, and can accommodate up to three 120 mm fans. The front mesh panel improves intake airflow, and the case dimensions of 222 mm (W) × 440 mm (D) × 385 mm (H) make it suitable for small workspaces.

Advantages

The compact footprint allows placement in tight work areas without sacrificing support for standard ATX power supplies. A mesh front panel combined with support for up to three 120 mm fans increases cooling potential, while compatibility with both 3.5" and 2.5" drives provides flexible storage options. The black finish offers a neutral, professional appearance that integrates with various setups.

How to use

Before assembly, verify the clearance for your graphics card and CPU cooler relative to the case dimensions. Install the ATX power supply in its compartment and secure the motherboard on standoffs, connecting all required power and peripheral cables. Mount storage devices in the designated 3.5" and 2.5" bays, install up to three 120 mm fans where mounting points are provided, and route cables through available openings to keep airflow unobstructed. Check that all connectors are properly seated before powering the system.

Recommendations

Check the length of your graphics card and the height of your CPU cooler against the Jonsbo U4 Mini dimensions before purchase. For balanced airflow in this compact Mini Tower, install at least one intake fan and ensure an exhaust path; use cable management to prevent obstruction of cool air intake.
