PC-kotelo Jonsbo D31 MESH Midi Tower valkoinen

The Jonsbo D31 MESH Midi Tower White is a compact PC case designed for Micro ATX, ITX and DTX builds. It features a mesh front panel and a side window that combine airflow and component visibility. The case supports ATX power supplies, one 3.5" drive bay, two 2.5" bays including a dedicated SSD slot, and flexible fan mounting options: up to three 120mm fans in the front, one 120mm fan at the rear, and two top fans supporting 120mm or 140mm sizes. Constructed from steel and finished in white, the chassis measures 205mm (W) x 440mm (D) x 347.5mm (H) and weighs 5.8 kg.

Advantages

The mesh front panel improves front-to-back airflow for cooling efficiency while the side window allows visual access to installed components. Support for multiple fan configurations and both 2.5" and 3.5" storage devices provides flexibility for gaming, workstations, and compact PC projects. The steel construction and compact dimensions offer a balance of durability and space-saving design suitable for smaller desks or limited workspace.

How to use

Install a compatible Micro ATX, ITX or DTX motherboard and mount an ATX power supply in the designated compartment. Fit storage devices into the 3.5" and 2.5" bays, using the dedicated SSD slot for a 2.5" drive as needed. Configure the cooling layout by installing up to three 120mm fans in the front, up to two 120/140mm fans on top, and a 120mm fan at the rear to establish a consistent airflow path. Route cables through available openings to maintain unobstructed airflow and to keep the interior organized.

Recommendations

For optimal cooling, use at least two intake fans at the front and one exhaust fan at the rear. When installing high-performance components, consider using 120mm fans with higher static pressure or adding top exhaust fans to assist heat removal. Ensure cable routing does not block airflow through the mesh front panel and use the side window to monitor component status and dust accumulation periodically.
