About this project
The A4-SFX case is a one-man project with the goal of creating the smallest case possible while still using high-end standardized components, such as Core i7 processors and powerful full-length GPUs, such as the GeForce GTX 980 Ti.
The result is a unique product that is much smaller than all competing cases. This case is perfect for SFF (Small Form Factor) enthusiasts, those who need a highly portable system, developers who require a case with a smaller footprint due to limited desk space, and gamers who want a high-end PC experience in their living room.
A number of creative ideas were needed to devise the case. Using a PCIe extender allowed for the most prominent design feature of this case, which is the location of the GPU behind the motherboard. The A4-SFX will come with the highest quality PCIe extender on the market, made by 3M, which allows for PCIe Gen3 and Gen4 support.
The case allows for easy mounting of either SFX or SFX-L power supplies. The PSU is located in the front of the chassis.
Depending on the size of the PSU, up to two 2.5” HDDs or SSDs can be mounted in the drive bay. The drive bay could potentially be mounted with rubber spacers to reduce vibration. A third drive can be mounted behind the front cover.
Every component is able to cool itself by getting fresh air directly from the outside. Hot air in the case will move to the top and then outside without the need of an extra fan. This principle works perfectly and results in an amazing cooling efficiency compared to other cases.

The A4-SFX has been reviewed by two of the largest German computer hardware sites. We are proud to have the rare "Recommended" Computerbase award. Please refer to the the articles below:.
- Golem.de: "You could not pack Gaming-Hardware any smaller"
- Computerbase: "...nowadays unique and deserves a special tribute"
DAN Cases UG (haftungsbeschränkt) has partnered with the best in the industry for the A4-SFX. The all-aluminum body will be manufactured by Lian Li in Taiwan per their highest quality standards. The PCIe extender will be supplied by 3M. The extender uses 3M's patented Twin Axial technology, and is widely recognized as the most reliable PCIe extender on the market. A commitment to quality lies at the core of our business philosophy.
In the name of transparency, we offer a cost breakdown graphic.
The initial Kickstarter run will be limited to 1700 cases. This restriction is necessary to guarantee quick delivery.
Every A4-SFX will feature a sticker with a production number. It will not be possible to reserve a number. Every case will be assigned a random number between 1 and 1700.
DAN Cases UG (haftungsbeschränkt) will ship to the countries listed below. If your country is not on the list, please contact us following a successful campaign, and we will find a solution for you.
As a special thank you to all Kickstarter backers, the A4-SFX will come with a 2-year warranty!
We will ship with DHL from Germany. Shipments will be insured and feature live tracking.
EU-based customers are required to pay the German 19% VAT tax. The tax is included in the overall case price and will not incur an additional increase.
Customers outside of the EU will not pay the 19% German VAT, but may have to cover local taxes. To make reward tiers handling easier, the VAT tax will be cleared with shipping costs for those customers. Therefore, they can expect to pay much less in shipping charges.
We've come a long way since the inception of the A4-SFX. See our past milestones below, as well as what the future holds should the project be funded.
If more than 1000 cases are sold during the Kickstarter campaign, there will be future availability of the A4-SFX. Otherwise, we will focus on new small-form-factor projects. This may be your only chance to get a A4-SFX, so don't wait!
Orders will be limited to 2 cases. Only a second Kickstarter account will give you the option to gain further rewards. We will provide 4 reward tiers: For 230€ you can order the black or silver version of the A4-SFX; For 460€ you can order 2 black, 2 silver, or one of each.
If interested in spare parts for modding, please contact us after a successful campaign.
A project like this couldn’t be done by a single person, so I would like to thank all who helped make the A4-SFX the great product that it is.
Risks and challenges
As with all products being mass produced for the first time we know that sometimes unforeseen scenarios can occur. Should this happen we promise our backers that we will do everything and work hard to deliver on spec and as quickly as possible.Learn about accountability on Kickstarter
