PC Case Jonsbo C6 Black ITX, micro ATX

The Jonsbo C6 Black is a compact PC case designed for ITX and micro ATX motherboards, offering a small footprint of 202 mm width, 266 mm depth and 295.2 mm height. Constructed from steel with a black finish, the case accommodates both 3.5" HDD and 2.5" SSD storage options, and supports an ATX power supply. Front-panel connectivity includes one USB 3.2 Gen 1 Type-A port. The design provides flexibility for cooling with support for 120 mm and 140 mm fans on the top and bottom, making the Jonsbo C6 Black suitable for compact system builds that require solid airflow and modest component compatibility.

Advantages

The steel construction offers structural rigidity while keeping overall weight low at approximately 2.3 kg. Its compact dimensions and support for Micro ATX and ITX motherboards make it suitable for small form factor systems without sacrificing standard storage options, including one 3.5" bay and two 2.5" bays. Support for an ATX power supply allows use of common PSUs rather than requiring SFX units. Cooling flexibility with mounts for 120 mm and 140 mm fans on top and bottom helps maintain airflow in tight spaces. A single USB 3.2 Gen 1 Type-A port on the front panel provides high-speed connectivity for peripherals.

Suitable for

• Compact home or office desktops where space is limited
• Small form factor gaming builds with Micro ATX or ITX motherboards
• HTPC or living-room computers requiring a discrete black case
• Systems that need both 3.5" HDD and 2.5" SSD storage options

How to use

Install a Micro ATX or ITX motherboard onto the provided standoffs, fit an ATX power supply into the designated compartment, and mount storage drives into the single 3.5" bay or two 2.5" bays as required. Position cooling fans in the top and bottom mounts according to preferred airflow direction and route cables to maintain unobstructed airflow. Connect the front-panel USB 3.2 Gen 1 Type-A port to the motherboard header. Close the case panels and place the assembled system in a location that allows adequate ventilation around the top and bottom fan positions.

Recommendations

For reliable thermal performance, use at least one intake and one exhaust fan in the supported 120 mm or 140 mm positions and keep cable routing tidy to minimise airflow obstruction. Use a low-profile CPU cooler if using high-performance components in this compact steel chassis. Verify PSU length compatibility before assembly, as space is limited and only ATX power supplies are supported.
