Description
Expert Features
- Powerful Cooling from the First Build: The factory-installed airflow system gives gamers an effective intake-and-exhaust foundation without immediately needing a separate fan set.
- Breathing Room for High-Performance Hardware: The open-front design helps powerful graphics cards and processors receive fresh air during demanding gaming and creative workloads.
- Less Restrictive Front Intake: The finely engineered mesh offers an open air path without the bulky appearance of traditional protective grilles.
- Focused GPU Cooling Upgrades: A dedicated internal fan-mounting area lets builders direct additional cooling toward the graphics card rather than relying entirely on front-to-back case airflow.
- Clean High-End Liquid-Cooled Builds: A separate top cooling zone lets builders showcase a premium CPU liquid cooler while keeping the factory front-fan configuration intact.
- Hidden Cabling with Rear-Connect Boards: Support for compatible reverse-connector motherboards makes it easier to achieve a professional-looking interior with fewer visible wires.
- Comfortable Installation of Large Components: Its roomy internal layout accommodates enthusiast graphics cards, substantial air coolers and powerful ATX power supplies without demanding a full-tower footprint.
- Elegant White Showcase Styling: The bright finish, restrained D-RGB accents and transparent side window complement coordinated white, silver or contrasting-color gaming hardware.
- Lighting Without Decorative Overload: Factory fan illumination and a horizontal case-lighting strip provide visual character while leaving the hardware itself as the centerpiece.
- Adaptable to Different Cooling Priorities: Builders can pursue quiet everyday airflow, a liquid-cooled gaming system or an airflow-intensive configuration for demanding GPUs.
- More Organized Builds: Behind-the-motherboard cable-management space helps keep unused cables away from the visible chamber and main airflow paths.
- Designed for Future Hardware Changes: Flexible motherboard, storage and expansion support makes it easier to refresh the PC without replacing the chassis.
- Showcase Access Without Sacrificing Cooling: The tempered-glass window highlights expensive internal components while the mesh front prioritizes practical ventilation.
- Convenient Peripheral Connectivity: Modern front connections allow quick access to external storage, gaming accessories and headsets.
- Customizable D-RGB Ecosystem: Compatible Phanteks accessories and lighting-control options let builders coordinate their visual theme as the system evolves.
- Optional Matrix Display Personalization: The separately sold Matrix 600 upgrade adds another customization option without requiring a different chassis.
- Useful for Gaming and Creator Systems: Its balanced cooling layout suits compatible gaming PCs, editing systems and demanding multipurpose desktops.
- An Elegant Alternative to Panoramic Cases: The Eclipse G400A prioritizes purposeful airflow, clean structure and an attractive illuminated interior instead of maximizing glass coverage.
