ATX computer case Darkflash DS900WS — mid-tower, no fans, black

Darkflash DS900WS — a black ATX mid-tower case supplied without fans, designed to accommodate ATX, Micro-ATX and Mini-ITX motherboards. The interior provides space for a graphics card up to 425 mm long and CPU coolers up to 170 mm tall. The chassis supports multiple drive options and a tempered glass left panel to display internal components. The bare-fan delivery enables builders to choose their own fan configuration or install liquid-cooling radiators to meet specific thermal and acoustic goals.

Advantages

The DS900WS offers flexible cooling capacity with mounting points for up to twelve 120 mm fans and support for front and top radiators, allowing both air- and liquid-cooling setups. A tempered glass side panel and a partial metal-mesh right panel balance component visibility with ventilation. The case layout provides space for two 3.5" drives and two 2.5" drives, seven expansion slots and a bottom-mounted power supply arrangement for standard interior organization. Removable magnetic mesh panels on top and bottom simplify maintenance.

Suitable for

• Custom gaming PC builds with dedicated GPU and aftermarket cooling
• Workstations requiring multiple drives and expansion cards
• Silent or liquid-cooled systems where fans are selected separately
• Showcase builds using tempered glass side panel

How to use

Install a compatible motherboard (ATX, Micro-ATX or Mini-ITX) on the standoffs and mount the power supply at the bottom in the designated compartment. Fit storage drives into the 3.5" and 2.5" mounting locations and insert expansion cards into the seven PCI-E slots. When planning cooling, measure clearance for the chosen CPU cooler and graphics card, then install fans or radiators in the front, top, side or bottom positions as required. Use the tempered glass side panel to access and check component connections; magnetic mesh panels can be removed for cleaning.

Usage recommendations

For optimal airflow, combine front intake fans with top and rear exhaust fans and consider a front 240 mm or top 360 mm radiator for liquid cooling. Select fans with appropriate thickness and power to ensure clearance for the GPU and radiators. Regularly clean the magnetic mesh filters to maintain ventilation efficiency and check that cable routing does not obstruct airflow paths.
