PC Case GIGABYTE C400 Midi Tower Black

The AORUS C400 GLASS mid-tower case features an optimized vertical airflow design that promotes rapid convection from bottom to top, improving heat dissipation. Its vented bottom, top and front panels provide ample intake airflow for internal cooling. With a compact ~40L volume, the chassis supports ATX motherboards, up to 360 mm liquid cooling radiators and thick, power-hungry graphics cards while maintaining a space-saving footprint. The case includes a 4 mm black tempered glass side panel, RGB Fusion lighting with 16.7M colors, an ARGB & PWM connector hub, detachable dust filters and a front I/O with USB 3.2 Gen2 Type-C.

Advantages

The vertical airflow layout increases convection speed to achieve more efficient cooling without requiring larger case dimensions. Compact ~40L size balances space saving and broad hardware compatibility, including support for ATX boards, 360 mm radiators and vertical GPU installation. The 4 mm tempered glass side panel is non-drilled for greater safety and easier removal. Built-in ARGB lighting with 16.7 million colors and a hub with five 5V 3-pin and five PWM connectors simplifies RGB and fan expansion. Tool-free modular panels and detachable fan/radiator bracket simplify assembly and upgrades. Magnetic and removable dust filters make maintenance fast and keep airflow optimal.

How to use

Remove the front, top or side panels without tools to install or upgrade components. Mount the motherboard, PSU and storage according to standard ATX layout, and install up to a 360 mm radiator on supported top or front positions. Use the detachable top bracket for fan or radiator installation to make alignment and fastening easier. Connect ARGB strips and fans to the built-in hub (5V 3-pin for ARGB, PWM for fan control) and link the hub to the motherboard header for lighting and PWM synchronization. Reattach the tempered glass panel carefully by aligning mounting points before securing it.

Recommendations

For optimal airflow and cooling performance, use a balanced configuration of intake fans at the front/bottom and exhaust at the top; keep magnetic and bottom filters clean to maintain unobstructed airflow. When installing a vertically mounted GPU, verify clearance and PCIe riser compatibility prior to assembly.
