Story
The original crowdsourced PC case.
The M1 started with a simple idea: motivated by the shortcomings of the enclosures that had come before, it set forth to be better in form and function. From the overall aesthetic design, down to the smallest detail, every facet was subject to the scrutiny and feedback of hobbyists, DIY'ers, and average users alike. The outcome of that effort? A 12.7L enclosure that sets itself apart with a unique combination of capability and flexibility, in a deceptively small and appealingly understated package.

Design
A handsome desktop you can actually put on your desk.
With its sleek, subtly-faceted brushed aluminum front panel, the M1 presents a refined, minimalist face to the world. An angular, arched cutout exposes the front USB and audio combo port, flanking the central power button, whose dual-color LED glows crisply – but not overly bright – when powered. Side and top panels are perforated with symmetrical ventilation areas, ensuring both visual harmony and proper system airflow. And fully toolless exterior panels allow easy access to the interior, while keeping the clean, smooth surfaces free of the visual clutter of screws or fasteners.

Performance
The biggest limitation is your imagination.
Designed for mini-ITX motherboards, the M1 nevertheless sports features shared by much larger enclosures. Full-length dual and triple-slot video cards can be installed with ease via large openings in the chassis. Top-down CPU coolers with 120mm or 140mm fans can be used in the M1, up to 130mm in height. All-in-one coolers with 120mm or even 240mm radiators can also be mounted internally. And – for the truly hardcore – the M1 allows for custom water cooling loops using a slim 240mm radiator, providing greatly reduced noise or additional overclocking headroom. Never before has this level of capability been possible in a enclosure of this size. High performance, low noise, and small size is no longer a "choose two" proposition.

Construction
Idealistic design. Everyday practicality.
Coming in at a svelte 12.7 liters in volume, the all-aluminum chassis has the proportions and features of much larger enclosures. Appearing as a conventional tower enclosure on a much reduced scale, the M1 enjoys a footprint that's substantially smaller than many cube-style small form factor enclosures. And, through its use of 1.5mm high-grade aluminum, its compactness and weightlessness don't come at the expense of rigidity, making the M1 easy to travel with or pack into a carry-on.
