The DA6 is a vertical open frame ITX case designed to provide the ideal platform for showcasing computer components. This open-frame design, combined with the unique approach to mounting hardware, means the DA6 has incredible support for the ever-increasing size and cooling demands of gaming hardware whilst still maintaining SFF conformity.

The main structure is formed from 19mm stainless steel tubes, creating an unbroken wrap-around frame that defines the body, feet and handles. This tubular theme continues to many other elements of the case to create a cohesive design. Beyond simply a style choice, the tubes play an integral part in not only the structure but also functionality, serving as support surfaces for fitting components when combined with the universal brackets.

The open-frame design not only allows for unrestricted airflow but combined with the ability to utilise 4 sides for mounting, gives unrivaled cooling potential. Each side has a tube to tube aperture of 150mm (166 without the brackets) ideal for 140mm fans (or smaller) to be mounted between them.

Staying within the confines of SSF volume whilst including support for ever-larger GPUs meant introducing compromises that we didn’t just want to concede, so we decided to release 2 versions of the DA6, the standard (just called DA6) and the DA6 XL.

The XL maintains the same footprint but the added height allows for GPUs up to 358mm in length leaving room for even the largest cards and some breathing room for potentially bigger next-gen cards.

A compact form is an efficient one, that is something we have always focused on. Staying true to SFF was critical but we also didn’t want to limit the potential of this case, especially considering its ideal for showcasing your GPU.

The DA6 stays true to SFF volume but the DA6 XL with its additional 35mm of height, allows for oversized cards to be installed whilst still maintaining the same footprint.

The case is designed around the use of tubes, the main structure is forms an unbroken wrap around frame that defines the body, feet and handles. The usage of tubes or rods continues to the motherboard posts and extends to the universal brackets that comprise of cylindrical mounts and even smaller rods that form the bracket. This creates a cohesive and simple design that whilst minimalist, doesn’t feel cheap thanks to the use of premium materials and finishes.
Whilst the CPU might be at the heart of every PC, the GPU has become the visual centrepiece of every performance system. Highlighting this was one of the main motivations for the open design of the DA6. There is simply no better way to fully appreciate your hardware without negatively impacting cooling performance (talking about you TG!) than an open case. Beyond just having an unrestricted view of the GPU, we wanted it to be perfectly positioned irrespective of the different sizes being used, so we incorporated an adjustable mounting solution. This gives the GPU x-axis movement for precise alignment of the card to the centreline of the case.

An open frame design removes many of the limitation and performance restrictions of a conventional enclosure. This allows the choice of components to be less dependent on size and more on the performance requirements.

The DA6 has plenty of room for a large downdraft cooler with 105mm in height up to the edge of the case but there is nothing stopping you from going all out with the tallest tower cooler you can get your hands on.

Whilst not specifically designed for water cooling, there are no real restrictions and radiators up to 280mm can be fitted.

Thinking of going fanless? We don’t actually make any fanless CPU coolers because we believe the case is critical and integral to correct fanless operation but …. the DA6 might just be the perfect companion for those fanless CPU coolers.

It almost wouldn’t be a Streacom case if it didn’t feature a unique way of mounting hardware, the DA6 is no exception featuring universal brackets that are more versatile than ever. Free to move along the entire length of the case and on all 4 sides, they allow for extremely granular placement of components and can accommodate the mounting of virtually anything as long as it physically fits (being an open case, good chance it will), opening up a whole world of possibilities. The brackets support 2.5″, 3.5″ drives, SFX and ATX PSUs with incredible versatility in terms of placement and orientation.
One of the features included on all ‘D’ series cases is port modularity. This allows for improved case personalisation and reduces obsolescence by providing an upgrade path for future standards. The DA6 comes fitted with a power button +  type-c module,  by default located on the bottom panel but it also features 2 additional module locations on the top panel. These can be used as an alternative to the bottom placement or used to add additional ports according to your exact needs and motherboard port features. We are committed to this modular platform and will build upon it by not only adding more port options but additional functionality such as biometric authentication.

    • Can I remove the top and bottom panels of the DA6?
      Unfortunately, due to the way the DA6 is constructed and assembled, it is not possible to remove the top and bottom panels from the tubes, it is a single assembly.
    • The RZ21B riser cable lock conflicts with the brackets on my DA6, what can I do?
      With some cards and positions, the plastic clip on the socket of the RZ21B riser cable conflicts with the brackets of the DA6. This can easily be resolved by removing the plastic clip as it is no really required to secure the card into the PCIe slot.
    • Can I polish the tubes of the DA6?
      The tubes of the DA6 are made from stainless steel so if you have accidentally made small scratches on the surface, they can be polished away using the appropriate tools. Whilst the tubes on the black DA6 are also made from stainless steel, they are powder coated so any repair would require a similar painting process and colour matching. Care should be taken not to damage the top and bottom panels when doing this as they are made from aluminium and feature an anodised surface that is less resilient than the steel tubes.
    • Are any IO modules is included with the case?
      By default and unless stated otherwise (or updated), a single 'Power Button + USB type-c/19PIN' module is included with the case and is pre-fitted to the bottom panel. Other modules are available to either replace or add to any of the other locations (on the top panel), but they are sold separately. There are currently 5 different modules available with various different cable options such as length or connector type
    • How many brackets are included with the DA6?
      The DA6 comes as standard with a total of 8 brackets, 2 on each side of the case. If more brackets are needed, they will be available from selected retailers or from our online shop
    • What is the largest size GPU that can fit inside the DA6?
      With the release of 4000 series cards, the size of GPUs has increased significantly (almost comically in some cases) and 3+ slot cards now appear to be the norm. The DA6 features support for a 3-slot bracket but the size of the card can extend beyond the bracket and to the edge of the case will accommodate cards that are 87mm thick (that is 4+ slots). If you dont mind the card sticking out beyond the edge of the case, then it's possible to support cards thicker than 87mm. The height of the card is limited to 143mm as it will then make contact with the PSU socket but this can be lowered (by removing the standoffs and then using an angled power cable to plug in) or removed entirely (by using a cable directly to the PSU) increasing that limit to 160mm. The image below shows the DA6 XL which supports cards up to 368mm in length but the same width and height dimensions apply to the DA6 but with a shorter length of 323mm.
    • Is there a riser cable included with the case?
      Due to the different PCIe revisions (e.g. Gen3 or Gen4) and with consideration for customers that might already have a compatible cable, we do NOT include one with the DA6. Instead, there will be an optional bundle comprising of the DA6 + Riser cable and the option to buy the riser cable separately. We do offer a riser cable which can be purchased from our retailers or directly from our online shop - RZ4
    • Can the case be used in a vertical orientation?
      The DA6 was very much designed to be used vertically but it is possible to use it horizontally. We included some rubber feet that are intended for the tubes, BUT can also be fitted to the aluminium upper/lower panels, allowing the case to be placed horizontally. Consideration must be taken with heavy components and how they are orientated when horizontal.
    • Without side panels, wont dust be an issue?
      In our experience, side panels and dust nets do very little to stop the build-up of dust around fans and high airflow areas of the case, they simply hide the problem. We think a better approach is simply cleaning any dust build up on a more regular basis, something that is considerably easier with an open-frame design and much more difficult to forget because you have a clear visual indication of the dust build-up.
    • What if I have a question that is not listed?
