Computer Case Jonsbo TK-3 ATX Black

The Jonsbo TK-3 ATX Black is a mid-tower computer case designed to accommodate full-size ATX motherboards and high-performance components. The case features a tempered glass side panel that provides a clear view of internal components, while the black exterior delivers a minimalist aesthetic. Internal layout supports multiple cooling configurations, cable routing channels, and space for longer graphics cards and tall CPU coolers.

Advantages

The case supports up to six fans and multiple liquid cooling radiator placements, enabling flexible thermal management for both air- and water-cooled systems. The tempered glass side panel combines durability with visibility to showcase component layout and lighting. Thoughtful cable management options simplify assembly and improve airflow. The chassis provides sufficient room for high-performance graphics cards and storage drives without compromising build neatness.

Suitable for

• Gaming PC builds requiring full-size ATX motherboard support
• High-performance workstations with discrete graphics cards
• Custom cooling setups including multiple fans and radiators
• PC enthusiasts who want a visible, clean internal layout via tempered glass

Key specifications

• Form factor compatibility: ATX, micro-ATX
• Side panel: tempered glass
• Cooling support: up to six 120mm fans or equivalent configurations; multiple radiator mounting locations for liquid cooling
• Drive bays: internal mounting locations for 2.5" and 3.5" drives
• Expansion slots: standard full-height expansion slot support for multiple PCIe cards
• Front I/O: front panel connectors for power, USB and audio (exact types depend on model configuration)
• Material: steel chassis with tempered glass

How to use

Install the motherboard on the provided standoff pattern compatible with ATX or micro-ATX form factors. Plan component placement for optimal airflow by positioning fans or radiators according to the intended cooling setup. Route cables through the dedicated channels and tie-down points to keep the interior tidy and unobstructed. Mount drives in the internal drive locations and secure expansion cards in the full-height slots. Verify clearances for GPU length and CPU cooler height before final assembly, then connect front panel I/O and power connectors.

Recommendations

For best thermal performance, configure intake fans at the front and bottom and exhaust fans at the top and rear; when using liquid cooling, ensure radiator placement does not conflict with RAM or GPU clearance. Use cable ties and the case's routing channels to maintain unobstructed airflow and to simplify maintenance and upgrades.
