The Jonsplus BO400CG is a high-quality showcase case for enthusiasts who want to stylishly display their hardware. Featuring a curved glass panel, modular design, and plenty of space for high-end components, it combines design, flexibility, and strong cooling performance.
- Curved-glass showcase impressively showcases hardware
- Supports ATX, Micro-ATX, and Mini-ITX motherboards for flexible builds
- Generous interior space for long GPUs and tall CPU coolers
- Modular covers allow customised looks and airflow adjustments
- Extensive fan and radiator options for powerful cooling
Panorama design with curved glass
The BO400CG clearly stands out from classic cases thanks to its curved glass panel. The gently curved glass surface creates a seamless panoramic look without harsh edges. This ensures your hardware is perfectly displayed from almost every angle.
High-quality materials and clever modularity
The sturdy aluminium frame not only gives the case a premium appearance but also aids heat dissipation. Tool-free removable side panels and interchangeable covers make assembly and later modifications easier. Cable management solutions ensure a clean look.
Plenty of space for high-end hardware and cooling
With support for graphics cards up to 435 mm, CPU coolers up to 173 mm, and power supplies up to 200 mm, the BO400CG is suitable for powerful systems. Up to ten 120 mm fans or multiple large radiators enable effective air or water cooling—even under heavy load.
