Endorfy is expanding its PC case lineup with a fresh entry aimed at compact builders: the Signum M30 Air and Signum M30 ARGB. These new mini tower cases mark the company’s first move into the micro ATX segment, offering a smaller footprint that still targets practical airflow, clean styling, and modern front-panel connectivity.
Two versions are launching side by side. The Signum M30 Air keeps things simple with no built-in lighting, while the Signum M30 ARGB adds fully customizable addressable RGB lighting. Beyond the lighting setup, the two cases share nearly identical specifications, so your decision mostly comes down to whether you want ARGB effects in your build.
Built for micro ATX and mini ITX motherboards, the Signum M30 series is clearly designed with space-conscious PC builders in mind. As expected with compact towers, there are limits you’ll want to plan around. Graphics cards are supported up to 345 mm in length, which should cover many mainstream and enthusiast GPUs, but it’s still worth checking your exact model before committing. For CPU cooling, the cases support air coolers up to 159 mm tall. Power supplies are supported up to 180 mm, and radiator support tops out at 240 mm—ideal for many popular AIO liquid coolers, especially if you’re building a balanced gaming or productivity system in a smaller chassis.
Storage support is also surprisingly flexible for a mini tower. The layout includes two 2.5-inch drive bays and two 3.5-inch drive bays, giving you room for a mix of SSDs and larger hard drives without feeling cramped.
Aesthetically, the Signum M30 cases lean toward a minimal, modern look instead of a loud “gaming” style, which makes them a strong fit for clean desk setups and understated builds. Cooling out of the box looks promising as well. Both cases include three Stratus 120 PWM fans, and the ARGB model gives those fans matching lighting. Endorfy also leaves room to expand cooling further, with space for up to four additional fans for builders who want to push airflow harder.
Airflow is a major focus here. The Signum M30 Air and M30 ARGB feature a mesh front panel combined with a perforated top panel to help fresh air move through the case more easily. Endorfy also positions this design as offering dust resistance, though real-world dust buildup and cooling efficiency will ultimately depend on conditions, configuration, and independent testing once more hands-on evaluations are available.
Up top, the front-panel I/O is well-equipped for a modern PC build. You get two USB 3.2 Gen 1 Type-A ports, one USB 3.2 Gen 2×2 Type-C port for high-speed devices, and two 3.5 mm audio combo jacks—handy for headsets and quick access without reaching around the back.
As for availability, both the Signum M30 Air and Signum M30 ARGB are launching in black for now. Pricing is expected to land around $100 to $110 in European markets, while broader availability—especially in the US—hasn’t been clearly confirmed at the time of writing.
