PC case Jonsplus BO400CG Midi-Tower ATX with Tempered Glass side panel, gunmetal grey

Jonsplus BO400CG is a Midi-Tower ATX PC case in gunmetal grey with a tempered glass side panel that reveals the internal layout and installed components. The case supports standard ATX, micro-ATX and mini-ITX motherboards and is engineered for straightforward assembly, cable routing and component access. With a minimalist exterior and transparent side, the BO400CG suits builds where clear interior visibility and practical airflow matter.

Advantages

The tempered glass side panel provides an unobstructed view of internal components while maintaining structural rigidity and a refined finish. The gunmetal grey exterior balances a neutral professional look with subtle styling. The interior layout allows for standard-sized graphics cards, multiple storage devices and efficient cable management. Front and top ventilation options are designed to support moderate cooling setups and fan installation. Tool-free access points and removable dust filters simplify maintenance and upgrades.

Suitable for

• Gaming builds with visible components and RGB lighting
• Home or office workstations requiring a compact ATX-compatible tower
• Upgrades and custom builds where easy access and cable routing are important
