The advanced Midi Tower gaming case features a reverse motherboard mounting technology that allows hiding all cables from the front side. This feature creates an exceptionally clean and aesthetic appearance within the glass "aquarium," showcasing components without the visual noise of wires. Dimensions of 415x288x438 mm provide spacious interior space for graphics cards up to 420 mm and large power supplies up to 220 mm, catering to the needs of the most demanding configurations.

The Jonsbo TK-3 case comes without pre-installed fans, giving enthusiasts complete freedom to create a personalized cooling system based on aesthetic and acoustic preferences. Ten mounting positions offer exceptional flexibility, including three side positions for additional component airflow. The reinforced steel construction with 0.7 mm wall thickness and a weight of 7.3 kg ensures reliability and minimization of vibrations. Support for large liquid cooling systems up to 360 mm at the top and bottom opens opportunities for extreme thermal management. The front panel is equipped with high-speed USB-C 3.2 gen2 and two USB 3.2 gen1 ports. Dust filters protect components, while rubberized feet provide stability.

Terrible case. Starting from the power button, ending with poor materials and engineering prob*ems. Some water coolers like the Arctic Freezer 3 360 cannot fit with the massive top radiators on the motherboard. The back panel is made as a monolith, this is the level of cases under €2,000.

Rear stick, power button, no mesh.
