Akasa Euler CMX Mini-ITX Fanless PC Case A-ITX61-S1B — black, mini chassis for passive-cooled systems

The Akasa Euler CMX Mini-ITX fanless PC case A-ITX61-S1B is a compact, black mini chassis engineered for passive-cooled systems that require silent operation and reliable heat dissipation. Designed to house Mini-ITX motherboards, the case offers a streamlined enclosure that uses its body as a heatsink, enabling wholly fanless configurations for home, office or industrial environments where low acoustic profile and dust-reduced operation are priorities.

Advantages

The chassis provides passive cooling through an all-metal construction that channels heat away from critical components without moving parts. Its small footprint makes it suitable for space-constrained setups while maintaining a professional black finish. The design reduces maintenance related to dust and fan failure, improves system longevity in continuous-operation scenarios, and eliminates fan noise for noise-sensitive applications.

Suitable for

• Silent home media PCs and HTPCs
• Office workstations where noise reduction is important
• Industrial or embedded systems requiring fanless operation
• Compact builds based on Mini-ITX motherboards

When it may not be suitable

This fanless chassis is intended for low- to moderate-power components; it may not be appropriate for high-TDP CPUs or graphics cards that generate substantial heat under load. Systems that require frequent internal airflow for active cooling, very high-performance gaming rigs, or builds with large add-in cards could exceed the passive thermal capacity of this enclosure.

Key specifications

• Form factor: Mini-ITX compatible
• Cooling concept: Passive (fanless) thermal design using metal chassis
• Exterior colour: Black
• Chassis type: Compact mini chassis for small form-factor builds

How to use

Install a compatible Mini-ITX motherboard and select low- to moderate-power components that match passive cooling requirements. Mount storage devices and power supply according to the case layout, ensuring thermal interfaces between heat-generating components and the chassis are correctly applied if the design requires direct contact. Place the assembled system in a location with adequate ambient airflow and avoid enclosing it in tight cabinets to maintain efficient passive heat dissipation.

What to consider before purchase

• Check CPU and GPU thermal design power (TDP) to confirm suitability for passive cooling
• Verify motherboard and storage drive compatibility with Mini-ITX layouts
• Plan component layout considering limited internal space and cooling contact points
• Consider ambient temperature and placement to ensure sufficient passive heat transfer

Recommendations

For best results, pair the case with low-power processors and efficient integrated graphics or passively cooled components, keep vents unobstructed, and monitor operating temperatures during initial use to confirm safe thermal behaviour.
