Antec C3 Constellation Series3 Mid Tower ARGB Tempered Glass ATX Case for Powerful, Stylish Builds

The Antec C3 CONSTELLATION SERIES3 Mid Tower ARGB Tempered Glass ATX Case is built for users who want a clean, modern look without sacrificing compatibility and cooling flexibility. Designed around a mid-tower layout, it supports ATX, Micro-ATX, and ITX motherboards, making it a practical choice for everything from everyday performance PCs to enthusiast gaming systems. With a tempered glass side panel, your components are showcased clearly, giving your setup a premium “showcase” feel compared to cases that use solid panels.

Premium Materials and a Clear Tempered Glass Side Panel

This case combines steel, plastic, and tempered glass to balance strength, durability, and visual appeal. The 4mm tempered glass side panel provides a clear view of your build, so RGB lighting and hardware details stand out. If you’re building a system where aesthetics matter—such as a desk setup or a workstation you’ll display—this windowed design helps you enjoy the look of your components every day.

Front Panel Convenience: USB 3.0, Type-C 3.2 Gen 2, and Audio

On the front panel, the case offers convenient connectivity for daily use. You get a USB 3.0 port, a Type-C 3.2 Gen 2 port, and a headphone/mic combo jack, along with a power access area and an LED control button. This front I/O setup is especially helpful for quick device connections—like plugging in a headset for gaming sessions or connecting modern peripherals that rely on Type-C—without reaching behind the desk.

Cooling System Designed for Stable Performance

Cooling is a key strength of the C3 CONSTELLATION SERIES3. It includes pre-installed fans and supports multiple airflow configurations to help maintain stable temperatures during long gaming sessions or heavy workloads. The case supports 3 x 120mm PWM ARGB reverse fans on the right side and 1 x 120mm PWM ARGB fan at the rear. PWM fan support helps deliver controlled airflow, which is useful when you want quieter operation at lower loads and stronger cooling when performance ramps up.

Fan Support and Radiator Support for Upgraded Cooling

Beyond the included fans, the case is designed to accommodate additional cooling options. It supports extensive radiator configurations for users who prefer liquid cooling or want improved thermal performance. This makes the Antec C3 a flexible platform for upgrading over time—whether you start with air cooling and later move to a radiator setup, or you plan a full ARGB liquid-cooling aesthetic from the beginning.

Drive Bays and Expansion for Flexible Storage and Upgrades

For storage and expansion, the case includes 1 x 3.5" / 2.5" drive bay and 3 x 2.5" drive bays, giving you room for a mix of drives depending on your build plan. It also provides 7 expansion slots, which is valuable if you plan to add expansion cards such as additional graphics capability, capture cards, or other PCIe accessories. Compared to more compact enclosures, this expansion capacity supports a wider range of upgrade paths.

Clear Compatibility for GPUs, CPU Coolers, and Power Supplies

The interior clearance is designed to fit demanding components. It supports graphics cards up to 415mm, CPU coolers up to 160mm, and PSUs up to 195mm. This is particularly useful when pairing a high-performance GPU with a larger air cooler, or when selecting a power supply that offers stable power delivery for modern builds. If you’re planning a future upgrade—like moving to a larger GPU or adding a more capable cooling solution—these supported sizes help reduce the risk of compatibility issues.

Who This Case Is For

The Antec C3 CONSTELLATION SERIES3 is a strong fit for gamers, PC enthusiasts, and professionals who want a mid-tower case with ARGB lighting support, a tempered glass viewing experience, and practical front-panel connectivity. It’s also a smart choice for builders who care about airflow planning—because the included PWM ARGB fans and radiator support make it easier to build a system that stays cool while looking great.
