The M1 sets itself apart with its unique combination of high performance capability and exceptional flexibility, in a deceptively small and appealingly understated package. Coming in at a svelte 12.6 liters in volume, the all-aluminum chassis has the proportions - and features - of a much larger case. Looking like a conventional tower case, but on a much reduced scale, the M1 has a footprint smaller than many "cube"-style small form-factor cases. It's compact enough to pack into a carry-on, while the featherweight, yet sturdy, aluminum construction makes it easy to travel with.
