Slim Specifications

Vertical Cooling with Reverse Airflow

The case supports up to six fans for effective cooling. It features two pre-installed 120mm PWM reverse fans on the PSU shroud. This setup pulls cool air from the bottom directly onto the GPU. A single 140mm PWM fan at the rear expels hot air. This creates a clear vertical airflow path from bottom to top. The design helps maintain lower component temperatures during demanding sessions.

Panoramic Curved Glass View

The three-sided tempered glass panels offer a wide, unobstructed view of your build. The curved design minimises visual breaks for a seamless look. This allows RGB lighting and component aesthetics to shine. The glass is 4mm thick for a premium feel. It is secured using studs for a tool-free installation.

Optimised Space for High-End Hardware

This case supports GPUs up to 450mm long and CPU coolers up to 180mm tall. The floating graphics card design prevents interference with side-mounted hardware. It also accommodates back-connect motherboards for a neater interior. The spacious interior simplifies building and future upgrades. You can fit a 360mm radiator on the top for liquid cooling.

Easy Tool-Free Maintenance

The side panels mount on studs with rear clip handles. This allows for quick, tool-free removal for access. The lower mesh panels detach via hooks for cleaning. The top panel also uses studs for easy installation. A pull-out bottom dust filter and a lower front filter provide protection.

Versatile PSU and Cable Management

The side-mounted PSU chamber accepts units up to 160mm long (excluding cables). A 13A high-spec extension cable is included for stable power. The PSU module is rotatable by 90 degrees for flexible installation. Behind the motherboard, there is up to 30mm of routing space.
