A4-SFX v1
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 1080.

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.

The case was developed in cooperation with the community from the following forums:

How It Works
A number of creative ideas were needed to create 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. This drive bay could potentially be mounted with rubber spacers to reduce vibration. A third drive can be mounted behind the front cover.

Thermal Concept
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.

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.

Initially the A4-SFX was a crowdfunded project on Kickstarter. The campaign was available between May and June in 2016. In this time, more than 1600 cases were sold on the Kickstarter platform. The project goal of 500 cases was reached in less than 40 minutes. The consumer demand was higher than expected so the campaign were nearly sold out.

Meanwhile there are thousands of new people interested in buying the A4-SFX. To give everybody the chance to get an A4-SFX we will be back on Kickstarter in May 2017.
