## Long description

The Jonsbo U4 PRO Midi Tower White is a compact PC case designed for mainstream desktop builds. It has a rear-mounted ATX power supply layout and supports Mini-ATX, ITX and ATX motherboards. The case accommodates one 3.5" hard drive and two 2.5" SSDs, and its mesh and steel construction with a side window balances airflow and component visibility. Physical dimensions are 205mm (width) × 395mm (depth) × 426mm (height), offering a small footprint while leaving space for standard components and up to three 120mm fans for cooling.
Advantages
The Jonsbo U4 PRO combines a mesh front and steel frame to provide improved ventilation without large external dimensions. Support for up to three 120mm fans allows flexible airflow configurations. A side window gives a clear view of internal components, and the rear power supply placement keeps cable routing straightforward. Built-in USB 3.2 Gen 1 Type-A connectivity offers modern external device access.

 Home or office desktop PCs where a compact Midi Tower is preferred

How to use
Install the chosen motherboard according to its form factor, secure the rear-mounted ATX power supply in the designated compartment, and mount storage devices in the provided 3.5" and 2.5" bays. Plan fan placement for up to three 120mm fans to create intake and exhaust airflow paths through the mesh front and vents. Route cables along the chassis edges and behind the motherboard tray where possible to maintain unobstructed airflow and a neat interior visible through the side window.
Usage recommendations
For optimal cooling, configure at least one intake fan at the front and one exhaust fan at the rear or top, and keep dust filters clean. Use the available 2.5" bays for SSDs to improve system responsiveness while placing bulk storage in the 3.5" bay. When installing high-profile CPU coolers or long graphics cards, verify clearance against the case depth and the side window area.
