M1: The original crowdfunded computer case

The story of the M1 started with a simple idea: motivated by the shortcomings of what had come before, we set forth to do better. The road would be winding, with many paths explored, and abandoned. A grassroots effort from its inception, the design process involved the community of PC enthusiasts at every step of the way. 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.

Through the support of the community, the project successfully raised funds to have a prototype built and tested. This paved the way to a second crowdfunding campaign for a full production run, contracted to the respected case manufacturer, Lian Li. Nearly one thousand first edition M1s were successfully delivered to people all around the world.

The road has been long, but the end result speaks to the passion, dedication, and support of the community and everyone involved. We'd like to offer our sincerest thanks to all of our supporters that have stuck with us and helped to bring this project to fruition.

Minimalist in size and style

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.

Small case, big performance

Designed for the mini-ITX motherboard form-factor for maximum space savings, the M1 nevertheless sports big-case features. Support for a dual-slot video card up to 12" is possible by utilizing the full length of the case; a specially designed opening at the front of the chassis allows long cards to be installed with ease.

While other cases in this size class place strict limits on CPU cooler size, the M1 is able to accommodate 120mm- and 140mm-fan top-down coolers of up to 130mm in height. Thanks to the innovative dual side 120mm fan bracket, a single 120mm or 240mm all-in-one water cooling radiator can also be mounted internally.

Custom water cooling

For the truly hardcore, the M1's dual side 120mm fan mount allows for custom water cooling loops using a slim 240mm radiator. Kits such as Swiftech's H220 and Cooler Master's Glacer 240L make it easy, and include everything needed for fully internal water cooling. They can even be expanded to include the GPU in the loop, for greatly reduced noise under load, or for more overclocking headroom. Never before has this level of capability been possible in a case of this size. With properly set up water cooling, high performance, low noise, and small size is no longer a "choose two" proposition.

Purposeful design

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 3.0 and HD audio ports, flanking the central power button, whose two-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.

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. The simple upward-facing slot at the front of the top panel provides discreet access to the neatly integrated mount for a slim slot-loading optical drive.

A multitude of possibilities

The M1 was designed with flexibility in mind, so while long video cards and water cooling support are great features, not everyone needs them. If 240mm radiator support isn't required, a pair of 3.5" drives can be installed on the side bracket. At the front of the chassis, either an upward-facing slim slot-loading optical drive or a 2.5" drive may be mounted.

The fully ventilated case floor presents further configuration options, featuring a total of six different mounts for a combination of drives and/or fans. A single 3.5" drive plus an 80 or 92mm fan, or a 2.5" drive plus a 120mm fan are just two of the possible combinations. Utilizing the included stacking bracket, two 2.5" drives may be used on any of the 2.5" mounts. In total, between the side bracket and chassis mounting, up to three 3.5" drives or five 2.5" drives may be mounted, depending on other components.

The M1 is designed primarily to use an SFX power supply, for which it is best suited. However, if the dual 3.5" HDD cage or 240mm radiator support aren't needed, and a short GPU under (195mm long) is used, then an ATX power supply can be installed with an included bracket.

Silent PC Review recommends the NCASE M1

Any trained eye can see that the NCASE M1 is a passion project even without knowing its origin story. It's absolutely gorgeous and surprisingly compact considering the components it supports. The well-conceived design is so detailed that everything fits with very little room leftover. The vertical slot-loading 5.25 inch drive in particular was ingenious as it hides the increasingly unpopular optical drive option without using up much space. It's also clear that usability was a key factor. Every panel pops-out easily, giving users unfettered access to every corner of the chassis during assembly, while the alternate drive/fan placements allow for some nice flexibility.

CPU Coolers

Coolers are limited to 130mm in height with the side bracket installed, and no fan installed.

  • When mounted, coolers cannot extend past the top edge of the motherboard by more than ~10mm. For many larger coolers, this limits motherboard choice to those with centrally-located sockets.
  • Large coolers that extend past the front of the board preclude use of the 3.5" HDD cage.

Rear exhaust cards are recommended, especially for cards with a TDP greater than 150W.

Maximum card length:

  • 317mm in slots 1 & 2
  • 279mm in slot 3

Maximum card height:

  • For cards up to 317mm, or for cards in the third slot: 111mm
  • For cards up to 292mm in length in the first or second slot: 140mm
  • For all cards: 120mm at the PCIe power connectors

Graphics cards with PCBs which extend to the full height at the corners will not fit in the M1, due to interference with the chassis. See this post for more information.

For more detailed GPU size limitations, refer to this diagram.


Optical Disc Drive Support

  • Slim slot-load drives up to 12.7mm thick are supported via vertical mounting with an ODD slotted top panel.

3 x 3.5" Mounts

  • 1 x 3.5" is available on the bottom of the enclosure
  • 2 x 3.5" is available via the removable side 3.5" HDD bracket, but can't be used with conjunction with a dual radiator or ATX PSU

3 x 2.5" Mounts

  • 1 x 2.5" is available inside the enclosure, towards the front
  • 1 x 2.5" is available behind the front panel, in lieu of an optical drive
  • 1 x 2.5" is available on the bottom of the enclosure, in lieu of a 3.5" drive
Liquid Cooling

Sealed liquid coolers, or integrated pump/block and radiator/reservoirs, are recommended. Only single 120mm or 240mm radiators are supported. A 240mm radiator on the side bracket precludes use of ATX power supplies or the dual 3.5" HDD cage.

Recommended maximum radiator length: 290mm, or less if installing a 2.5" drive at the front of the enclosure

Recommended maximum thickness of radiator & fans: 60mm

Power Supply

SFX PSU support is standard. Installation of SFX-L (SFX extended to 130mm long) power supplies is possible using the v3 and later SFX bracket, which has been revised specifically for models based on the Sirfa/High Power unit. These include:

  • The SilverStone SX500-LG
  • The Sharkoon SilentStorm SFX Gold
  • The High Power SFX-L500GD
  • The Chieftec SFX-500GD-C
  • The Scythe SPKRG-S500P

Due to the limited space available, SFX-L is a tight fit when used with long GPUs.

ATX PSU support is possible using the included bracket with the following limitations:

  • ATX PSU's can't be used with GPUs over 195mm long.
  • ATX PSU's can't be used with the dual 3.5" HDD cage or 240mm radiator mounted to the side bracket; a 120mm radiator is still possible to install over the motherboard area
  • Maximum recommended ATX PSU length: 160mm
  • The AC inlet orientation on some ATX power supplies may prevent the included angle plug from fitting, so it is crucial to check the orientation and location of the AC inlet to ensure compatibility. See this diagram for more information. The included AC cable uses a left-angle plug.

No fans or paper manual are included.

What's the difference between different versions of the M1?

Each version has a few minor revisions. You can see a list of changes here.

Can I turn the optical drive slot version into the no-ODD slot version if I get the slotless top panel?

Yes. The only difference is the top panel, which may be easily swapped out.

Are the panels compatible with a different version of the chassis (e.g., V2 chassis with V3 panels)?

Yes. All panel versions are compatible with all chassis versions.

There's no manual! What do all the screws do?
How do I remove the side panels?

The side, top, and front panels require no tools to remove. Using your fingertips, simply pull them away from the case by the edges.

There's no manual! What do all the screws do?

There are two types of drive mounting:

  • For the rounded keyhole mounts (2.5" mounts, one bottom 3.5" mount), attach the rubber softmounts and screws to the drive first, slide the drive into the keyholes.
  • For the spade-shaped keyhole mounts (on 3.5" HDD cage and one bottom 3.5" mount), insert the rubber softmount into the keyhole first, then screw the drive

Additionally there are small brackets included which allow 2.5" drives to be installed together in a stacked fashion.

Will [insert component here] fit in the M1?

Please see the compatibility section for size restrictions and links to more information.

A 240mm radiator can't possibly be enough to cool both a high end CPU and GPU, can it?

It most certainly can. Radiator requirements are often exaggerated, but this also has to do with expectations and what your goals are. A 240mm radiator and full water loop in the M1 can significantly lower the noise of the GPU, while keeping temperatures below stock.

Are there any accessories designed for the M1?

Yes! Demciflex offers magnetic filters specially designed for the M1. They can be purchased directly from their site. Additionally, other members of the community have spearheaded the development of the following accessories for the M1:

Please note NCASE has no affiliation with any of these individuals or companies.

Why isn't the M1 microATX? All you have to do is add a slot!

One of the primary design goals of the M1 was to be able to house, power, and cool high performance components, while being as small as reasonably possible. Mini-ITX is the smallest motherboard form-factor capable of supporting such a build, and is actually considerably smaller than mATX. In particular, the short length of mini-ITX is what allows the front-mounted power supply, and by extension, the side-mounted dual radiator. Keeping the same layout with mATX would result in a a significantly larger case.

MicroATX also has a higher set of requirements in regards to cooling and power delivery, necessitating a move to larger components (ATX PSUs) and less compact layouts to ensure good airflow.
