The Aptech R21-Glass ARGB Gaming Casing in White is a premium mid-tower chassis that blends modern aesthetics with practical performance. Featuring a sleek all-white finish and a large tempered glass side panel, this case beautifully showcases your PC components while keeping your setup stylish and clean .

Spacious Interior & Motherboard Compatibility

The R21-Glass is built around the G330 ATX chassis design, offering a spacious interior with dimensions of 365 x 200 x 455 mm . It fully supports standard ATX motherboards as well as smaller Micro-ATX boards, providing flexibility for various build configurations . The case features 7 expansion slots, allowing for multi-GPU setups or additional add-in cards.

Tempered Glass Showcase

The left side panel is constructed from durable tempered glass, secured with four screws, offering a crystal-clear view of your internal components . Whether you install RGB fans, LED strips, or simply want to admire your cable management, the glass panel transforms your PC into a visual centerpiece.

Cooling Configuration

Note: This case is sold without pre-installed cooling fans . However, it provides excellent cooling potential with support for up to four 120mm fans, allowing you to customize the airflow and RGB lighting to your preference . The split gaming case structure with a metal top cover and mesh front panel design promotes efficient heat dissipation.

Storage & Expansion

The R21-Glass provides ample storage options with dedicated mounts for two 2.5-inch SSDs and two 3.5-inch HDDs . This allows you to combine fast boot drives with high-capacity storage for games and media. The case does not include 5.25-inch ODD bays, maintaining a clean, modern front panel appearance .

Front I/O Connectivity

The front I/O panel includes one USB 3.0 port, two USB 2.0 ports, and HD Audio jacks for headphones and microphone . (Note: On some variants, the USB 3.0 port may be non-functional/fake; check with the retailer for confirmation) .

Durable Construction

Built with 0.45mm thick SPCC steel and finished with an all-white coating, the R21-Glass offers a durable yet lightweight chassis . The bottom-mounted PSU design includes a dedicated chamber to help with cable management and isolate heat from the power supply.
