EINAREX reveals PRISMA SM300 with powerful cooling in a compact design
EINAREX has launched the new PRISMA SM300, a compact microATX PC case made for users who want better airflow without giving up a modern and clean setup. The new chassis mixes strong cooling support with a panoramic glass design aimed at gaming and creator builds.
The PRISMA SM300 comes with a special angled bottom intake layout that pushes fresh air directly toward the graphics card. This design targets one of the hottest parts inside modern PCs and helps improve thermal performance during gaming and heavy workloads.

The company says the case was created to combine style and function in a simple way. Instead of adding extra design elements just for looks, the PRISMA SM300 focuses on practical airflow improvements while keeping a premium appearance.
Despite its smaller microATX size, the case still supports large hardware. Users can install graphics cards up to 400 mm long, CPU air coolers up to 160 mm tall, and side-mounted 360 mm liquid coolers. It also supports both microATX and Mini-ITX motherboards along with standard ATX power supplies.


Cooling is another major focus of the new chassis. The PRISMA SM300 supports up to nine fans and uses a dual-chamber internal layout to help separate airflow and manage cables more cleanly. The case also provides up to 90 mm of cable management space, making it easier for builders to create a neat setup.
For daily usability, EINAREX added several modern features, including a sliding tempered glass side panel, USB Type-C front connectivity, and an easy-access internal structure for simpler installation and upgrades.
The panoramic tempered glass panels allow users to fully display their hardware while still maintaining efficient airflow throughout the system.
