Darkflash TH285 computer case, ATX, white

The Darkflash TH285 computer case in white is an ATX mid-tower chassis designed for gaming and workstation builds. The case measures 426 mm x 285 mm x 403 mm and is constructed from 0.7 mm SPCC steel with a tempered glass side panel that exposes the interior. It ships with four pre-installed fans and supports up to seven fans in total, multiple radiator mounts and a bottom-mounted power supply to help manage airflow and cable routing. Drive and expansion provisions include bays for 2 HDDs and 3 SSDs and seven PCI expansion slots, while motherboard compatibility covers ATX, Micro-ATX and Mini-ITX boards.

Advantages

The TH285 offers a balance of airflow and component compatibility: four included fans plus space for up to seven provide flexible cooling layouts, and support for long graphics cards (up to 415 mm) and tall CPU coolers (up to 160 mm) accommodates high-performance parts. The tempered glass side panel provides a clear view of internal components, while the bottom-mounted PSU and integrated cable management improve internal neatness and thermal separation between heat sources. Multiple front-panel connectors including USB 3.0 and audio ports give convenient access to peripherals.

Suitable for

• Gaming PC builds with full-size ATX or smaller motherboards
• Workstation systems requiring multiple drives and long GPUs
• Air-cooling or compact custom water-cooling setups (radiators up to 360 mm bottom / 280 mm side)
• Systems where interior visibility and tidy cable routing are desired

How to use

Install the motherboard compatible with ATX, Micro-ATX or Mini-ITX standards onto the standoffs provided, then fit the power supply into the bottom compartment (maximum length 240 mm) and route cables through the dedicated channels for a tidy layout. Mount storage drives into the 3.5" and 2.5" bays or adapter brackets, install the graphics card (up to 415 mm) into the PCIe slots, and fit CPU cooling within the 160 mm height limit. Adjust fan positions or add additional fans and radiators according to the chosen cooling strategy, making sure airflow is unobstructed between intake and exhaust paths.

Recommendations

For balanced cooling, configure intake fans in the bottom and side positions and place exhaust fans at the rear and upper sections. When using water cooling, verify radiator thickness and clearance against installed components and route PSU cables behind the motherboard tray to maintain unobstructed airflow. Ensure that drive and fan placements do not interfere with long graphics cards, and use the tempered glass panel for visual inspection while the system is powered down.
