EINAREX proudly announces the launch of the new PRISMA SM300, a microATX panoramic chassis designed around one clear purpose: delivering optimized airflow performance through purposeful engineering. Built under the PRISMA family philosophy, the SM300 combines a compact dual-chamber layout with a distinctive angled bottom fan platform that directly targets GPU cooling performance. The result is a chassis that balances aesthetics, airflow efficiency, and modern hardware compatibility in a clean panoramic format.

"PRISMA SM300 represents our vision of creating products where every design choice serves a purpose," said Rafa, CEO of EINAREX. "We wanted to create a compact panoramic chassis that not only looks clean and modern but also improves thermal performance through structural design itself."Airflow Designed with Intent
At the core of the PRISMA SM300 is its angled bottom intake structure, specifically engineered to direct airflow toward the GPU area where modern systems generate the highest thermal load. Combined with support for up to 9 cooling fans and side-mounted 360 mm liquid cooling radiators, the SM300 is built to maintain stable airflow performance for high-end gaming and creator systems.

The chassis also features a full panoramic tempered glass design that showcases hardware without compromising thermal efficiency, creating a balance between visual presentation and practical cooling.

Compact Format Without Limitation
Despite its microATX footprint, the PRISMA SM300 is engineered for broad hardware compatibility. The chassis supports:

• microATX and Mini-ITX motherboards
• GPUs up to 400 mm in length
• CPU air coolers up to 160 mm in height
• ATX power supplies
• 360 mm side-mounted liquid cooling radiators

Its dual-chamber internal structure also provides up to 90 mm cable management space, helping builders achieve cleaner assembly and improved airflow separation.

Modern Building Experience
The PRISMA SM300 incorporates several usability-focused design elements to simplify the building process and improve everyday use, including:

• Sliding tempered glass side panel
• Tool-friendly internal access
• Optimized cable routing structure
• Bottom-focused airflow architecture

The chassis was developed following EINAREX's ongoing philosophy of creating products that combine functionality, aesthetics, and user-focused experience without unnecessary complexity.

Availability
The EINAREX PRISMA SM300 will be available through selected global distributors and partners. Availability may vary depending on region.
