The Euler CMX isn’t just another mini-ITX case—it’s a reimagining of how small systems can stay cool without fans. Targeting Intel’s Core Ultra series (and older 8th-gen CPUs), this 4-liter chassis from Akasa prioritizes silence and efficiency, making it a standout for low-TDP builds. With a built-in 220W power supply, M.2 heatsinks, and even wall-mounting support, it’s designed for users who need performance in tight spaces—whether that’s a home office, a lab, or a media center.
But the real innovation lies in its fanless design. While most compact cases rely on fans to handle heat, the Euler CMX uses a large aluminum thermal module to dissipate CPU heat through its chassis fins. This approach isn’t just about silence; it’s about longevity, ensuring stable temperatures for CPUs up to 35W TDP—perfect for Intel’s Core Ultra 5 (245KF) or Core Ultra 7 (270K) without compromising on airflow.
Key specs at a glance
- Form factor: Mini-ITX (248.6 x 205 x 78.5 mm)
- Volume: 4.0 liters
- CPU support: Intel 8th-gen to Core Ultra (up to 35W TDP)
- Cooling: Fanless, aluminum thermal module + M.2 heatsinks
- Power: Built-in 220W PSU (optional 150W external adapter)
- Mounting: VESA/wall-mount compatible
- Connectivity: USB 3.2 Gen 1, USB 2.0 (Type-A)
- Price: $187 (available in North America, Europe, UK, Asia)
The trade-off is clear: no fans mean quieter operation and lower maintenance, but the case is optimized for low-power CPUs. For higher-TDP parts (like the Core Ultra 9 285H at 35W or the Ryzen 9800X3D at 165W), a traditional fan-based case would be a safer bet. That said, the Euler CMX’s wall-mounting and compact size make it ideal for setups where space is at a premium—think under-desk media PCs or rack-mounted home servers.
Who should buy it?
This case is a niche but compelling choice for:
- Home lab enthusiasts building quiet, low-power test systems.
- Media center users who want a fanless, wall-mounted setup for HTPCs.
- Office workers needing a discreet, portable second machine.
- Budget-conscious builders who prioritize silence over raw performance.
For gamers or power users, the lack of fan cooling and limited PSU options (the 220W unit may struggle with high-end GPUs) could be dealbreakers. But for its target audience—those who value silence, portability, and efficiency—the Euler CMX delivers on all fronts. With no moving parts and a design that doubles as wall art, it’s a fresh take on the mini-ITX form factor.
