ASUS has introduced the Prime AP304, a panoramic ATX PC case aimed at builders who want high-end hardware to remain the centerpiece of a system. Its curved tempered-glass front and side panel, graphics-card support features, and airflow-focused layout combine showcase styling with compatibility for modern components. The case is offered in black or white, with an optional ARGB-equipped configuration.
Key takeaways
The Prime AP304’s main highlights include:
- Curved tempered glass wrapping from the front to the side for a broad component view.
- Support for graphics cards up to 420mm long and radiators up to 360mm.
- A patented slot vent designed to improve graphics-card cooling.
- Reinforced GPU support hardware, including a tool-free slot clamp.
- Optional pre-installed ARGB fans and Aura Sync integration.
- A top-mounted 20Gbps USB Type-C port and 33mm of cable-management space.
The design is clearly intended to balance visual presentation with practical support for large, power-hungry hardware.
A glass-focused showcase design
The AP304 uses a curved glass panel that flows continuously across the front and side of the chassis. ASUS says the panel is produced through a five-stage process that includes tempering for added strength and durability. An easy-detach rail is intended to make removing and reinstalling the panel simpler during upgrades or maintenance.
Inside, the primary component chamber appears visually separated from the power-supply area, creating a floating effect. This layout gives the graphics card a prominent position while leaving much of the system visible from multiple angles.
Built around graphics-card cooling and stability
A patented slot vent uses a three-sided ventilation structure to direct airflow toward the graphics card. The case also includes a reinforced graphics-card bracket that supports cards measuring between 300mm and 360mm and attaches with screws to limit movement and sag.
For additional flexibility, the patented slot clamp enables tool-free graphics-card installation. The chassis supports graphics cards up to 420mm overall, although builders should still verify clearance alongside front-mounted hardware and cable routing.
Cooling, compatibility and connectivity
The AP304 supports radiators up to 360mm long, including top-mounted liquid-cooling configurations. The ARGB version ships with four pre-installed fans, while reporting on the case indicates that these are 28mm-thick ASUS MR120 units designed to provide increased airflow. The lower chamber can also accommodate up to three fans for graphics-card-focused cooling.
A top I/O panel includes one USB Type-C port rated for transfer speeds of up to 20Gbps, two USB Type-A ports, and an audio jack. Behind the motherboard tray, 33mm of space is available for cable management, and the case supports power supplies up to 200mm long.
Availability and unanswered questions
ASUS has announced black and white versions, with configurations available either with or without pre-installed ARGB fans. The integrated lighting works with ASUS Aura Sync for coordinated illumination.
Pricing and release timing were not provided in the announcement. Early reporting also indicates that the case may not support ASUS BTF back-connect motherboards, an important consideration for builders planning a rear-connector system. ASUS has not published a value proposition or confirmed broader regional availability.
