Product information

Description

Light Base 900 FX Black is a spacious PC case with large transparent panels and integrated ARGB lighting designed to showcase high-end components. It ships with four pre-installed Light Wings fans and a 3 m ARGB LED strip (172 LEDs) with controller and supports motherboard ARGB synchronization. The chassis accommodates large cooling setups, E-ATX motherboards, multiple radiators and provides a two-chamber layout for tidy cable and drive management.

Advantages

The full-view front and side panels offer clear visibility of internal components while the 3 m LED strip and four ARGB fans provide multi-angle illumination. Reversible feet allow fast switching between upright and inverted or horizontal layouts. The case supports up to ten fans and multiple radiators (two 420 mm simultaneously plus an additional 360 mm in the side), and includes detachable radiator/fan brackets for simplified installation. Two ARGB/PWM hubs with 12 connectors and a flexible VGA holder improve cable management and prevent GPU sag in any orientation.

Key specifications

Pre-installed fans: 4 x Light Wings (3 x 140 mm side intake with reversed blades, 1 rear exhaust)
ARGB LED strip: 3 m, 172 LEDs, included controller, motherboard sync support
Motherboard support: up to E-ATX, supports backside connector designs (Asus BTF, MSI Project Zero, Gigabyte Project Stealth)
Radiator support: up to two 420 mm simultaneously; additional side radiator up to 360 mm (up to 3 radiators total)
Maximum fans: expandable up to 10
Drive/cable management: two-chamber design
Accessories: detachable top and bottom radiator/fan brackets, 2 ARGB + PWM hubs (12 connectors total), flexible VGA holder

How to use

Install your motherboard (up to E-ATX) and mount storage drives in the rear chamber to keep cables out of airflow paths. Attach radiators or fans to the detachable top, bottom, and side brackets as required; each top and bottom bracket fits a 420 mm radiator and the side supports up to 360 mm. Connect the ARGB strip and fans to the included hubs or to a compatible ARGB header on your motherboard for synchronization. Use the relocatable feet to change case orientation quickly and position the flexible VGA holder under the GPU to prevent sagging. Route cables through the back chamber for a tidy interior.

Recommendations

For optimal cooling and showcase aesthetics, use motherboard ARGB synchronization when available, install radiators in top and bottom positions for best airflow, and secure the GPU with the included VGA holder. Check compatibility of very large GPUs and radiators with the case’s internal layout before final assembly.
