Small Case, Big Ideas

The Jonsbo A4 is a phenomenal chassis for building a small and powerful gaming PC. Boasting an innovative dual chamber design, there is room for a wide variety of modern hardware. The left side chamber has ample room for a powerful GPU, with two expansion slots and 325mm of clearance.

The right side of the case is where you can install your motherboard and storage. The motherboard tray is compatible with Mini-ITX boards, and offers a CPU clearance of 71mm, perfect for supporting down draft coolers. The Jonsbo A4 has two mounting points for 2.5" SSDs next to the motherboard. For those that don’t require extra storage, this case includes two decorative acrylic plates to be installed here instead. One features the Jonsbo logo laser etched into its surface, whilst the second can be used to store spare screws and an Allen Wrench.

Vertical Cooling

With its four side panels boasting solid construction, the Jonsbo A4 utilises a highly efficient vertical cooling design. Fresh air is drawn in through the base of the case, utilising two 120mm fans. These have ample access to fresh air, as the base of the case is raised up by four removable screw-in magnetic feet.

With the two-chamber design, fresh air is delivered independently to both the motherboard and GPU chamber, maximising their cooling. From here, air is drawn up to the top of the case, where it can be exhausted out the top using two more 120mm fans. Alternatively, a 240mm radiator can be installed at the top, ideal for AIO cooling solutions.

Style Focused

The Jonsbo A4 has a bold aesthetic, making it the perfect complement to any gaming set-up. The front of the case features a simple and elegant design, with minimal front I/O and a sandblasted aluminium finish. The top of the case features a beautiful vent, that has been precisely cut using CNC techniques to facilitate airflow. Meanwhile, the rear of the case has a chic design, only featuring cutouts for your rear I/O and GPU connectors.

What’s more, the Jonsbo A4 is an excellent chassis for showing off your gaming hardware. The A4 is equipped with two tempered glass side panels. These offer an excellent view into both chambers of the case, allowing you to display either your motherboard or GPU, depending on how you lay out your chassis.
