Computerbehuizing Jonsbo D300 ATX zwart

The Jonsbo D300 ATX Black is a mid-tower computer case designed to house standard ATX motherboards and common gaming or workstation components. Featuring tempered glass side and front panels, the chassis provides a clear view of internal hardware while maintaining a compact footprint. The interior layout supports multiple cooling configurations and offers space for standard-length graphics cards, tower CPU coolers, and several storage drives, enabling balanced airflow and component access.

Advantages

The tempered glass panels combine visibility with dust resistance and a simplified aesthetic. The D300's internal layout is oriented to facilitate cable routing and component installation, reducing assembly time. Support for front, top, and rear fan or radiator mounting gives flexibility for air or liquid cooling setups. The black finish provides a neutral appearance that integrates with a variety of build styles and peripherals.

Suitable for

• Gaming builds with single high-performance graphics cards
• Home or office ATX systems needing a compact mid-tower case
• Custom cooling configurations using multiple fans or radiators
• Showcase builds that benefit from tempered glass visibility

Key specifications

• Form factor: Mid-tower compatible with ATX, micro-ATX, and mini-ITX motherboards
• Exterior: Tempered glass front and side panels with black finish
• Storage support: Multiple 2.5" and 3.5" drive mounting options
• Cooling support: Mounting points for front, top and rear fans; radiator compatibility in common sizes
• Expansion: Several PCI expansion slots for standard-length graphics cards
• Front I/O: Standard front panel ports and power/reset controls

How to use

Install the motherboard onto the pre-stamped standoffs and secure it with appropriate screws. Fit the power supply into the designated compartment and route the main cables through the provided cutouts to the motherboard and components. Mount storage drives into their trays or cages and secure expansion cards into the PCI slots. Configure fans or radiators in the supported mounting locations, ensuring clear airflow paths from front intake to rear/top exhaust. Close the tempered glass panels after verifying cable management and connector seating.

Recommendations

For optimal cooling, install at least one intake fan at the front and one exhaust fan at the rear; consider a top exhaust or radiator for high-performance CPUs or GPUs. Use cable ties and the case’s routing channels to keep cables clear of airflow paths and maintain unobstructed ventilation. Clean the tempered glass and dust filters regularly to preserve airflow and component visibility.
