Product information

Description

The ENDORFY Regnum 400 Air Tower Black is a tower-style PC case designed to combine roomy internal space with strong airflow in a compact footprint (472 × 220 × 442 mm). The case supports multiple radiator sizes (120/240/280/360 mm), accommodates up to four drives (2× 2.5" + 2× 3.5" or 4× 2.5"), and fits Mini-ITX, Micro-ATX and ATX motherboards. The package includes four black Stratus 120 PWM fans to ensure effective cooling while a tempered-glass side panel provides a clear view of installed components.

Advantages

Mesh front panel and included Stratus 120 PWM fans create high airflow for lower internal temperatures. Spacious interior supports long GPUs (up to 370 mm) and a 275 mm power supply while still allowing room for large radiators and multiple storage drives. Tempered-glass side window offers a clean presentation of components without compromising structure. Compact external dimensions keep the case suitable for typical desks and setups.

Suitable for

Gaming PC builds that require strong airflow and room for large GPUs
Workstations needing multiple storage drives and compatibility with ATX motherboards
Custom water-cooling setups using 240/280 mm top or 360 mm front radiators
Users who want a visible interior via tempered-glass side panel

How to use

Install the motherboard on the provided standoffs, fit the power supply into the PSU chamber and route cables through the grommeted openings. Mount storage drives in the designated 2.5" or 3.5" bays and secure the GPU in the PCIe slots, ensuring overall clearance does not exceed 370 mm. Install additional fans or radiators as required: the front supports a 360 mm radiator while the top accepts 240/280 mm radiators. Connect the included Stratus 120 PWM fans to the motherboard or a fan hub for PWM control and verify airflow direction before powering the system.

Usage recommendations

For optimal cooling, use the mesh front panel with intake fans and exhaust at the rear/top; maintain unobstructed airflow paths, and prefer PWM fan headers for automatic speed control. When fitting multiple radiators or large GPUs, check clearances for PSU length and drive cage positions before final assembly.
