Utilizing a PCIe riser to achieve an innovative back-to-back design, the A4-SFX is a modern and remarkably compact enclosure that's able to support enthusiast-grade components within a svelte 7.25L design. Highlights of the A4-SFX include it's all-aluminum construction, efficient space utilization, and thermal seperation of the CPU and GPU.

The A4-SFX: Created by the community

The A4-SFX enclosure originated as a one-man project, with the goal of creating the smallest case possible that could support high-end standardized components - from Intel Core i7 processors, to powerful full-length GPUs like the GeForce GTX 1080.

The result of years of work and several generations of design, the A4-SFX today stands alone as a product that's dramatically smaller than almost all competing enclosures. As such, it's an ideal solution for SFF enthusiasts; those who need a highly portable system; users who want to reclaim desk space; and gamers who want a high-end PC experience in the living room or in other space-constrained contexts.

Design

How it works

This case uses what we refer to as a sandwich hardware layout. Using a PCIe® extender allowes for the most prominent design feature of this case, which is the location of the GPU behind the motherboard. The A4-SFX comes with a high quality PCIe® extender, made by 3M™, which allows for PCIe® 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 is mounted with rubber spacers to reduce vibration and noise. A third 2.5" drive can be mounted behind the front cover.

GPUs without a protective backplate can safely be used in the case. A thin plastic film is installed to prevent electrical short with the aluminum chassis or the PSU.

Finally, with the new version of the A4-SFX you will be able to mount a 92mm fan or a 92mm All-In-One water cooling solution in place of the drive bay.

Performance

Thermal concept

Through the compartmentalization of the primary components of the computer, the PSU, CPU/motherboard and GPU each enjoy distinct air inlets and outlets for cooling. Because of this, every component is able to efficiently cool itself by drawing fresh air directly from the exterior, and then channeling heated air upward and outside of the case. Even without dedicated exhaust fans, this layout is a key contributor to the impressive cooling efficiency of the A4-SFX, compared to most other enclosures.
