## Summary description

ENDORFY Regnum 400 ARGB is a tower PC case in black with tempered glass side panel and multi-colour ARGB illumination. It supports ATX, micro ATX and mini-ITX motherboards, up to 37 cm graphics cards and 16.2 cm CPU coolers.

## Long description

The ENDORFY Regnum 400 ARGB Tower Black is a mid-tower PC case that balances internal space with a compact external footprint. It includes a tempered-glass side window, preinstalled Stratus 120 PWM fans with ARGB lighting, and support for multiple drive configurations and cooling layouts. The case accepts Mini-ITX, Micro-ATX and ATX motherboards, accommodates up to four 2.5" drives (or two 2.5" plus two 3.5"), and can fit a GPU up to 370 mm in length. Radiator support includes 240/280 mm on top and up to 360 mm on the front, providing options for air and liquid cooling.
Advantages
The Regnum 400 ARGB provides a clear view of internal components through a tempered-glass window and comes with four preinstalled Stratus 120 PWM ARGB fans to simplify lighting and airflow. Its interior is roomy enough to house larger graphics cards and multiple drives while still fitting into a standard tower footprint. The case supports versatile cooling setups—either up to eight air fans or various radiator configurations—helping maintain lower component temperatures under load.
Suitable for
Building a mid-tower gaming PC with ARGB lighting
Workstations requiring multiple storage drives (2.5" and 3.5")
Systems with large GPUs (up to 370 mm)
Air-cooled or liquid-cooled builds with top/f ront radiators

How to use
Install the chosen motherboard (Mini-ITX, Micro-ATX or ATX) on the standoffs, fit the power supply into the designated compartment and mount storage drives in the provided trays or brackets. Insert the GPU (maximum 370 mm) into the PCIe slots and route cables through the case cutouts for neat cable management. Connect the preinstalled Stratus ARGB fans to the motherboard or an ARGB controller and attach the front-panel USB connectors to the motherboard headers. If using liquid cooling, install compatible radiators on the top (240/280 mm) or front (up to 360 mm) following the radiator and fan clearance guidelines.
Usage recommendations
For optimal cooling and quieter operation, balance airflow by using intake fans at the front and exhaust at the top/rear. When using ARGB features, connect fans to an ARGB header or controller compatible with your motherboard to synchronize lighting. Verify GPU and radiator clearances before final assembly to ensure compatibility.
