Jonsbo C4
An elegantly beautiful case ideal for building a luminous gaming rig
The mid-tower Jonsbo C4 catches eyes at the first sight, featuring clean front panel design, all black interior, and tempered glass panels on both side. Its interior provides adequate space to support ATX motherboard, CPU cooler up to 167mm in height, VGA card up to 300mm long, and up to seven expansion cards. In terms of cooling, the C4 supports three 120mm intake fans at front left side (behind the left glass panel), two 120 intake fans at the bottom, and one 120 rear exhaust fan (included), and features six precision cuts on the right glass panel to ensure advanced air circulation. Water cooling radiator can also be installed. The power button, two USB 3.0 ports and two audio jacks are located at the top of the left panel for easy access, as well as preserving the clean look of the front panel.
If you're looking for striking style, practical functionalities and robust cooling in your case search, look no farther.
Exquisite Look
The I/O panel with power button and 2 x USB 3.0 can be found on the left panel and does not interfere with the intentionally unobtrusive look of the front. A special feature is the two windows from "tempered glass", which decorate the case and give the user a look at the installed hardware. The left side panel is slightly tinted, while the right side part is largely opaque - only the CNC-milled recesses allow the inside of the case to be seen.


Roomy Interior
The C4 provides space for ATX mainboards and standard ATX power supplies, and has a total of 7 expansion slots. The power supply is installed behind an inconspicuous PSU cover. The cover has large air holes on the underside, so that the power supply can draw air from below. This additionally supports the venting of the interior. Generous cable management makes it easy to hide the cables.
The high-quality and well-built tower case can be equipped with VGA cards up to of 300 mm in length and CPU coolers up to a height of 167 mm. The versatile housing provides enough space for two 2.5-inch SSDs and two 3.5-inch drives or up to four 2.5-inch data storage devices. Two 2.5-inch SSDs can be installed on the back of the mainboard tray. Another 2.5 or 3.5-inch HDD / SSD can be found behind the power supply cover. Finally, a 2.5 or 3.5 inch drive can be attached to the HDD holder inside the enclosure. The 3.5-inch drives are mounted with rubber insulation.



The intelligent interior design of the C4 provides enough space for a powerful ventilation system or an extensive water cooling system. Behind the front is a fan rack, which allows you to mount up to three 120 mm fans behind the left side of the unit. The right-hand side has a total of six long-shaped CNC cutouts, which means that the air supply is easily possible despite the "tempered glass" side part.

The fan rack also offers the possibility of installing a 120/240/360 mm radiator on the inside, without being visible from the outside. The fans can be mounted on the outside, while the radiator is installed at the inside of the rack. It is also possible to use a push/pull configuration thanks to the enormous space available to the rear side part. On the bottom of the housing are mounting holes for a water cooling pump.
Two 120 mm fans or a 240 mm radiator/compact water cooling system can also be installed on the bottom of the case. The distance to the mainboard is sufficient enough to even allow the installation of thick radiators.
