Its interior accommodates graphics cards up to 425 mm long and CPU coolers up to 170 mm tall. The case accepts up to 12x120 mm fans, supports water cooling radiators (front up to 240 mm, top up to 360 mm) and offers space for two 3.5" HDDs and two 2.5" SSDs. A tempered glass left panel reveals the interior, while seven PCI-E expansion slots and top I/O ports (USB 3.0, USB 2.0 x2, HD Audio) provide practical connectivity.

Advantages

The DS900WS ATX delivers broad cooling options with room for multiple fans and radiators, a compact but roomy 470 x 218 x 454 mm steel chassis, and a tempered glass side panel for component visibility. The case includes flexible drive mounting for both HDD and SSD storage, seven expansion slots and magnetic mesh panels for easier maintenance and improved airflow.

How to use

Install the motherboard (ATX/M-ATX/ITX) with the power supply mounted at the bottom. Fit the storage drives into the designated 3.5" and 2.5" bays, mount the graphics card horizontally if it fits within 425 mm, and install a CPU cooler no taller than 170 mm. For air cooling, populate fan positions up to the supported 120 mm locations; for liquid cooling, install compatible radiators in the front (up to 240 mm) or top (up to 360 mm). Route cables behind the motherboard tray and use the magnetic mesh panels for easy access during assembly and maintenance.

Usage recommendations

To optimize airflow, combine front intake fans with top/rear exhausts and keep cable routing tidy. When installing large GPUs or multiple drives, verify clearances before final assembly and use the tempered glass panel to monitor component condition and RGB lighting if applicable.
