Computer case DarkFlash B275 PRO (white) with 6 fans

DarkFlash B275 PRO (white) with 6 fans is a mid-tower computer case designed to provide clear interior visibility and out-of-the-box airflow. The case features tempered glass panels that create a 270° panoramic view of installed components and ships with six 120 mm fans preinstalled to form a ready cooling configuration. Compact external dimensions (354 x 275 x 425 mm) accommodate standard ATX power supplies, motherboards in ATX/Micro-ATX/Mini-ITX form factors and expansion cards up to 410 mm in length while supporting CPU coolers up to 160 mm tall and storage combinations of one 3.5" HDD and up to two 2.5" SSDs.

Advantages

The case combines a full-view tempered glass aesthetic with a steel chassis made from 0.5 mm SPCC for structural rigidity and modular interior access for easier assembly and upgrades. Six preinstalled 120 mm fans reduce initial build time and provide immediate airflow; additional mounting points support up to nine fans or multiple radiators for water cooling. Top and bottom dust filters limit dust intake and simplify maintenance. Front and side ventilation openings are integrated to improve airflow pathways across GPU and CPU areas.

Suitable for

• Mid-range and compact gaming PC builds that benefit from showcased components and active airflow.
• Home or small office workstations requiring reliable cooling and a compact footprint.
• Systems using air or AIO liquid cooling with space for 240/280/360 mm radiators in several mounting locations.
• Builders who want a visually open chassis for RGB lighting, custom cooling loops, or streaming setups.

How to use

Install the selected motherboard and power supply according to standard ATX/Micro-ATX/Mini-ITX mounting points, route cables through the provided openings and secure storage devices in the dedicated 3.5" and 2.5" bays. Mount the graphics card in a rear expansion slot and verify clearance for cards up to 410 mm. If using an aftermarket CPU cooler, ensure total height does not exceed 160 mm. The preinstalled fans are connected to the included fan headers or hub; connect front I/O and audio to the motherboard headers. Use the top and bottom dust filters to reduce debris intake; remove them for cleaning when the system is powered down.

Usage recommendations

For balanced airflow, configure intake fans at the front and bottom and exhaust at the top and rear. When installing multiple radiators or high-TDP components, verify clearance and consider fan curves or a fan controller to balance cooling performance and acoustic levels. Regularly clean dust filters and internal surfaces to maintain thermal efficiency and prolong component lifespan.
