## Long description

The ENDORFY Regnum 400 ARGB is a black tower PC case that combines practical storage and cooling options with a tempered-glass side window for component visibility. It supports Mini-ITX, Micro-ATX and ATX motherboards, can accommodate up to four 2.5" drives (or two 2.5" and two 3.5"), and fits graphics cards up to 370 mm. The case includes pre-installed ARGB Stratus 120 PWM fans and offers radiator support for 240/280 mm on top and up to 360 mm at the front, providing flexibility for both air and liquid cooling builds.
Advantages
The Regnum 400 ARGB provides a spacious interior in a compact tower footprint, a tempered glass side panel for easy component viewing, and multiple mounting options for fans and radiators to maintain low temperatures under load. It ships with four Stratus 120 PWM ARGB fans for immediate lighting and airflow, and supports a range of storage configurations and E-ATX-compatible cooling solutions without compromising internal space.
Suitable for
Gaming and multimedia builds requiring good cooling and visible components
Workstations that need multiple storage drives (2.5" and 3.5")
Custom builds using air cooling with multiple fans or liquid cooling with 240/280 mm top or 360 mm front radiators

How to use
Install the motherboard (Mini-ITX, Micro-ATX or ATX) on the standoffs, mount storage drives in the dedicated 2.5"/3.5" bays, and route cables through the provided openings for tidy cable management. Fit the GPU up to 370 mm in length and choose either air cooling with up to eight fans or install compatible radiators: 240/280 mm on the top or up to 360 mm on the front. Connect the included Stratus 120 PWM ARGB fans to the motherboard or an ARGB controller to enable lighting and PWM fan control.
Usage recommendations
For best airflow, keep front ventilation unobstructed and use the pre-installed ARGB fans in intake at the front and the rear fan as exhaust. When installing a front 360 mm radiator, verify clearance for drive cages and cable routing; if using high-end GPUs, ensure sufficient clearance and consider front radiator placement and fan orientation to balance cooling and component fit.
