MPN T9 BLACK PCIe 5.0 |

The Jonsbo T9 combines a compact design with a subtle and timeless look and strong hardware support. Despite its space-saving design, the mini case offers room for an ITX motherboard, a 3-slot graphics card up to 310 mm, and two 120 mm fans.

  • Elegant and space-saving design fits into any setup
  • Graphics cards up to 310 mm with vertical mounting and PCIe 5.0 riser cable
  • Two 120 mm fans provide optimal cooling performance
  • Hidden power supply cabling for a clean look
  • Dust filters protect your hardware from dust and dirt

The Jonsbo T9: Timeless elegance meets minimal design

Whether a mini workstation or a compact gaming PC – with the Jonsbo T9 you have a variety of options. Thanks to its understated design, the case fits into any possible setup – whether in black or silver. At just over 30 centimetres in length, the case is barely larger than a modern gaming console.

Powerful hardware in the smallest space

The compact Jonsbo T9 easily accommodates an ITX motherboard, two 120 mm fans, and even a graphics card up to three slots wide. This makes the case suitable for high-performance builds, such as with an RTX 5090 Founders Edition. Despite its small size, you don’t have to compromise on high-end components.

The vertical mounting of your graphics card using the included PCIe 5.0 riser cable allows for particularly efficient use of space. Thanks to the 3-stage adjustment of the dual chambers, you can flexibly decide: either more space for a wide GPU or for a CPU cooler up to 78 mm high.

Optimal cooling with protection against dust and dirt

To ensure that the airflow from the case and your components is not negatively affected by dust, the Jonsbo T9 features a total of three dust filters. These protect against dust ingress on the sides and the top panel, enabling smooth and effectively cooled operation.
