Expecting restock
Premium Midi Tower case, primarily created for enthusiasts who do not seek compromises when building a showcase system. The key feature of the model is the use of high-quality aluminum in the construction, which advantageously distinguishes it from standard steel chassis. The aquarium-style design with seamless tempered glass panels on the front and side provides a panoramic view of the components, turning the assembled PC into an exhibit piece. The case comes without fans, offering experienced builders maximum freedom to create a custom cooling system. The cooling potential is huge: there are 10 fan slots and a unique opportunity to simultaneously install three 360-mm radiators (at the top, side, and bottom). The internal architecture of the Jonsbo BO400 case differs from mo...st counterparts with an atypical top placement of the power supply. This solution affects the layout and cable management, and support for motherboards with reverse connection allows for an ideal appearance. The chassis is designed for the most powerful components: supporting graphics cards up to 435 mm in length and CPU coolers up to 173 mm. A graphics card holder is included. The front panel features a modern set of ports, including two USB 3.2 gen1 and a high-speed USB-C 3.2 gen2.
