Computer case Darkflash C280 (black) with 7 preinstalled fans

The DarkFlash C280 (black) with 7 preinstalled fans is a mid-tower computer case engineered to accommodate a wide range of desktop PC builds. It supports E-ATX, ATX (including back-connect for ATX and M-ATX), Micro-ATX and ITX motherboards, and provides space for graphics cards up to 420 mm long and CPU coolers up to 155 mm tall. Constructed from 0.7 mm SPCC steel and fitted with tempered glass panels in a 270° panoramic layout, the C280 combines structural rigidity with expansive interior visibility. With dimensions of 443 × 277 × 426 mm and seven included 120 mm fans, the case is prepared for immediate airflow-optimized configurations.

Advantages

The C280 offers a 270° panoramic glass design that enables full-side visibility for component showcase and easier internal access. Its modular ventilation layout supports up to ten 120 mm fans or multiple radiator sizes for flexible cooling solutions. The interior provides multiple mounting options including vertical GPU placement, a multifunctional bracket for storage drives, and back-connect motherboard support to simplify cable routing. Dust filters on the top and bottom and removable panels improve maintenance and long-term cleanliness.

Suitable for

• Custom gaming PCs requiring enhanced airflow for CPU and GPU cooling
• Workstations for video editing, 3D rendering or graphics work that need robust cooling and large GPU support
• Home or office desktops where component visibility and cable management are priorities
• Compact to large builds using ITX, M-ATX, ATX or E-ATX motherboards

How to use

Install the chosen motherboard according to its standoffs and secure it inside the case, then mount the power supply in the PSU area and route primary cables using the back-connect passages for ATX and M-ATX where applicable. Fit storage drives into the multifunctional bracket (three 2.5" or two 3.5" slots) and install the graphics card either horizontally or vertically depending on the preferred layout and available riser. Attach CPU cooler up to 155 mm height and arrange fans or radiators based on the intended airflow: intake from the front/side/bottom and exhaust through the top/rear. Connect front-panel I/O (USB, audio, power/reset) to the motherboard headers before closing panels and secure dust filters in place for initial system operation.

Usage recommendations

For optimal thermal performance, configure a balanced airflow setup with slightly higher intake capacity than exhaust, place radiators where they will receive fresh air (top or side depending on radiator size), and use the included seven 120 mm fans as a baseline, adding up to three more fans if you fit multiple high-power components. Regularly clean the top and bottom dust filters and plan cable routing through the back-connect channels to maintain unobstructed airflow and easier maintenance.
