RAIJINTEK Paean Desktop PC Case — Black Transparent, ATX/Micro-ATX/Mini-ITX, 4x USB 3.2 Gen1, 3x3.5 inch + 3x2.5 inch bays

RAIJINTEK Paean is a desktop ATX chassis with a black anodized aluminum and SPCC construction and transparent tempered glass panels. Designed as a dual-chamber open-frame/bench table, it supports ATX, Micro-ATX and Mini-ITX motherboards and provides space for multiple storage drives, a bottom-mounted power supply and front-facing connectivity with four USB 3.2 Gen1 Type-A ports. With dimensions of 286 × 587 × 417 mm and a weight of 10.8 kg, the Paean combines a robust aluminum base plate and 5 mm tempered glass to present interior components while accommodating high-end cooling and cable-routing options.

Advantages

The dual-chamber open-frame layout separates motherboard, CPU and GPU from secondary components to improve airflow and simplify cable management. Thick aluminum base plate and tempered glass panels give a rigid, stable platform and clear visibility of the interior for component placement and water-cooling layouts. Tool-free installations for drives and other components speed up assembly and maintenance, while support for 240/280/360 mm radiators plus clearances for long graphics cards and standard ATX power supplies make the case suitable for performance builds.

Suitable for

• Custom desktop PCs using ATX, Micro-ATX or Mini-ITX motherboards
• Enthusiast water-cooling setups with 240/280/360 mm radiators
• Systems requiring multiple storage drives (3×3.5" and 3×2.5")
• Showcase builds where interior visibility through tempered glass is desired
• High-performance GPU configurations including multi-card setups

Key specifications

• Form factor support: ATX, Micro-ATX, Mini-ITX
• Case dimensions: 286 × 587 × 417 mm
• Weight: 10.8 kg
• Materials: SPCC steel, aluminum, 5.0 mm tempered glass
• Drive bays: 3×3.5" and 3×2.5"
• External ports: 4× USB 3.2 Gen1 Type-A

• Maximum GPU length: up to 310 mm (supports longer up to 400 mm under specific layout)
• Maximum PSU length: up to 200 mm
• Maximum CPU cooler height: up to 140 mm

How to use

Install the chosen motherboard (ATX, Micro-ATX or Mini-ITX) on the designated standoffs on the upper/front chamber, route power and data cables through the rear chamber to keep the layout tidy, and mount the power supply in the bottom-mounted area with the allowed maximum length. Fit storage devices into the 3.5" and 2.5" bays using the tool-free mounting points and secure tempered glass panels after component installation. For water-cooling, position radiators up to 360 mm in supported locations and use the bench-style open-frame arrangement to place reservoirs, pumps and tubing with the included mounting options.

Recommendations

To maintain stability and airflow, use components within the specified length and height limits (GPU up to 310 mm typical, PSU up to 200 mm, CPU cooler up to 140 mm) and plan radiator placement before assembly. Use anti-vibration mounts for mechanical drives and ensure tempered glass panels are handled carefully and secured in place. For complex water-cooling builds, verify clearance when using vertical reservoirs or custom pump arrangements to avoid interference with long graphics cards.
