Product information

Description

The Jonsbo U4 Mini Mini Tower in black is a compact PC case designed for small-form-factor builds that require efficient airflow and straightforward assembly. Constructed from steel with a tempered glass side window, the chassis supports Mini-ATX and ITX motherboards and accepts a standard ATX power supply. With internal space arranged to accommodate one 3.5" drive and one 2.5" drive, and compatibility with common 120mm and 140mm fan sizes, the case balances storage versatility and cooling potential within dimensions of 222mm (W) × 440mm (D) × 385mm (H).

Advantages

The case offers a compact footprint suitable for desks and small setups while maintaining support for full-length ATX power supplies. Tempered glass on the side panel allows component visibility without compromising rigidity from the steel construction. Inclusion of front I/O with a USB 3.2 Gen 1 Type-A port provides a modern connectivity option. Support for multiple fan layouts (120mm and 140mm) enables adaptable cooling configurations to match different component and airflow requirements.

Suitable for

  • Compact desktop or home office builds where space is limited
  • Mini-ATX and ITX gaming or productivity systems
  • Systems requiring at least one 3.5" HDD and one 2.5" SSD
  • Builds prioritizing visible components via a tempered glass side window

Key specifications

  • Form factor: Mini Tower
  • Supported motherboards: Mini-ATX, ITX
  • Power supply: supports ATX power supplies
  • Drive bays: 1 × 3.5" bay, 1 × 2.5" bay
  • Fan support: compatible with 120mm and 140mm fans
  • Materials: steel chassis with tempered glass side panel
  • Front I/O: 1 × USB 3.2 Gen 1 (Type-A)
  • Colour: black
  • External dimensions (W×D×H): 222mm × 440mm × 385mm

How to use

Install a compatible Mini-ATX or ITX motherboard onto the standoffs inside the chassis, then mount an ATX power supply in the designated compartment. Fit storage devices into the single 3.5" and single 2.5" bays using the provided mounting points. Configure cooling by installing 120mm or 140mm fans in supported locations and route cables to the rear or along the chassis edges to maintain airflow. Connect the case front I/O USB 3.2 Gen 1 Type-A to the motherboard header for front-panel connectivity.

Usage recommendations

For improved cooling performance, use a balanced configuration of intake and exhaust fans (for example, one front intake and one rear exhaust) and keep cable routing tidy to avoid obstructing airflow. When installing a high-profile CPU cooler or long GPU, verify component clearance against the case's internal layout before final assembly.
