Separated Cabinet Design

The JONSBO TK-4 BLACK is a separated cabinet ATX PC case built for builders who want clear internal visibility and flexible hardware layout. Its bi-bent surround-view glass panels use 4mm glass with a 2H hardness protection film applied to the surfaces. The chassis combines SGCC 1.0mm steel, plastic, glass and AL 2.0mm aluminium construction in a black finish. It accepts ITX, M-ATX and ATX motherboards including back-connect designs.

Cooling Capacity And Limits

The case provides 11 fan positions: top and bottom areas support three 120mm or three 140mm fans each, the side supports three 120mm or three 140mm fans, and the rear takes two 92mm fans. Dual 420mm radiator mounting positions are available at the top and bottom. Large-area cooling grilles on the back panel improve airflow. Maximum GPU length is 460mm, maximum CPU cooler height is 175mm, and maximum PSU length is 200mm.

Upgrade Path And Fit

This case replaces standard ATX towers that lack separated-chamber layouts or back-connect motherboard support. The jump is worth it when you need dual 420mm AIO mounting, extensive fan placement options, and a glass showcase design with 4mm panels. It is not for builders who require more than two internal 3.5in drive bays or more than two internal 2.5in bays, or who need front-panel dust filters beyond the rear filter provided.

Questions about this item

Will the 460 mm GPU limit and 200 mm PSU limit still let me reuse my current full-size graphics card and ATX power supply?

The case accepts graphics cards up to 460 mm long and ATX power supplies up to 200 mm deep, so most standard full-size cards and PSUs will fit without modification.

How can I verify the 420 mm radiator mounts and 11 fan positions are all recognised by the system after assembly?

Check BIOS fan headers for each connected fan, confirm pump speed on the AIO header, and monitor coolant temperatures under load to ensure both 420 mm radiator locations and all 11 mounting points are active.

Does the package include the 4 mm bi-bent glass panels and the 2H hardness protection film, or do I need to buy them separately?

The 4 mm bi-bent surround-view glass panels and the pre-applied 2H hardness explosion-proof film are installed on the case from the factory; nothing extra is required for the glass.
