How Can This Much Hardware Fit Within This Outline?
The Streacom DA6 is a vertical open-frame case supporting Mini-ITX and Deep Mini-ITX motherboards. The standard model measures 215 × 215 × 431mm.
Multiplying those external dimensions gives an approximate volume of 19.9L.
That figure should be treated as a calculation from the exterior measurements, not as an officially stated internal capacity.
The remarkable part is the relationship between that approximately 19.9L exterior envelope and its expansion-card support.
The standard DA6 accepts cards up to 323mm long, while the DA6 XL raises the limit to 358mm. The XL retains the same footprint and adds 35mm of height, producing external dimensions of 215 × 215 × 466mm.
Calculated from those dimensions, its exterior volume is approximately 21.5L.
Instead of forcing every build into one compromise, Streacom offers a standard version and a taller XL version that preserves the footprint while creating room for a longer graphics card.
A Case Built Around the GPU
Expansion-card support is listed as triple-slot. Maximum card length is 323mm in the standard model and 358mm in the XL.
The GPU mount is adjustable along the x-axis, allowing the card to be aligned with the case centreline. Because the frame has no conventional side panels, the graphics card remains visible rather than sitting behind an enclosure wall.
The official description presents this unrestricted view, together with reduced obstruction around the hardware, as a central motivation for the design.
For practical planning, the phrase “triple-slot” should not be treated as a complete physical measurement. As a general consideration, slot-thickness terminology can vary between products.
A builder should therefore check the actual body of the card, any cooler overhang, and the route required by its power cables. The official text does not identify a supported riser generation, so no particular interface generation can be promised from the supplied information.
If a build uses a riser, its specification has to be checked separately.
Card length is also only one part of fitting a GPU. A cable needs an appropriate bending radius, and fitting the card does not automatically prove that a connector can be routed without an abrupt bend.
This is a general integration issue rather than a DA6-specific measurement. The movable universal brackets provide broad positioning freedom along the full length and on all 4 sides of the case, but the official material does not state the clearance required by any particular card-and-cable combination.
The Meaning of the 105mm Cooler Figure
CPU-cooler clearance is stated as 105mm to the edge of the case. Because this is an open frame, the official description says a taller cooler can be used when it is allowed to protrude beyond that edge.
Streacom specifically describes room for a large downdraft cooler and says that the open structure does not stop the builder from using a very tall tower cooler. Compatibility with individual cooler models, however, is not officially listed.
Memory-module height is not the only interaction worth checking in an air-cooled build. As a general rule, a cooler fan or its mounting hardware may contact nearby components before the memory heat spreader itself becomes the limiting factor.
Moving a fan upward can also change how far the assembly protrudes. These are layout checks for the completed configuration; the source does not provide model-specific compatibility results.
The DA6 was not specifically designed as a water-cooling case, but it supports 120mm, 140mm, 240mm, and 280mm radiators. Its maximum stated radiator size is 280mm.
Each side provides a 150mm tube-to-tube opening with the brackets installed, increasing to 166mm without them, and can accept fans of 140mm or smaller. The universal-bracket maximum is stated as 150mm.
Airflow Without Conventional Walls
The DA6 approaches airflow by removing the conventional enclosure panels rather than by defining fixed intake and exhaust openings. Streacom says the open frame enables unrestricted airflow, while the ability to use 4 sides for mounting expands the available cooling arrangements.
This is fundamentally different from a closed case with a prescribed front-to-back airflow path.
Open construction does not automatically make every component’s intake conditions ideal. In compact systems generally, the temperature of the air entering a cooler can have a direct effect on component temperature.
A builder should consider whether air leaving a radiator, GPU, or CPU cooler will immediately become the intake air for another device. Selecting components around heat output, and building with power limits in mind to balance temperature and noise, can be a useful general strategy.
The official DA6 material does not state a recommended power limit or publish configuration-specific temperature data.
Power-Supply and Storage Flexibility
Power-supply support includes SFX, SFX-L, and ATX units, with a maximum PSU length of 185mm. The universal brackets are described as allowing considerable freedom in PSU placement and orientation.
The official material does not specify a recommended wattage or power-supply capacity, so the required output must be determined from the installed components.
Storage support covers 2.5-inch and 3.5-inch drives.
There is no fixed official drive-count figure: the quantity depends on the other hardware installed and the remaining space. That wording matters because the same universal mounting concept that creates flexibility also makes capacity configuration-dependent.
Even a 2.5-inch drive can affect the route taken by cooling air when placed near a fan or cooler.
That is a general airflow consideration, not a claim that a particular DA6 mounting point will cause an obstruction. In practice, the useful mounting position is the one that leaves workable paths for both air and cables, rather than merely any position where a bracket can hold the drive.
A Frame Formed from 19mm Stainless-Steel Tubes
The main structure is formed from 19mm stainless-steel tubes. They create an unbroken wrap-around frame defining the body, feet, and handles.
The tubes are not merely decorative: with the universal brackets, they also become support surfaces for installed components. The tubular theme continues through the motherboard posts and the cylindrical mounts and smaller rods used by the brackets.
The 19mm figure describes the tubes; it is not a panel-thickness specification. Official panel thickness: not stated.
The individual materials used for every part outside the main structure are also not officially stated in the supplied text. It would therefore be incorrect to infer that the unspecified parts are aluminium.
As a general workshop consideration, aluminium threads can be easier to damage, but the source does not establish that the relevant DA6 parts are made from aluminium.
The official net weight is 2.5kg, while gross packed weight is 3.4kg.
The form-factor description identifies SFF and mentions tower or horizontal orientation.
Universal Brackets Change the Assembly Process
The universal brackets can move along the entire length of the frame and can be used on all 4 sides. They support 2.5-inch and 3.5-inch drives as well as SFX and ATX power supplies, with placement and orientation left flexible.
This means the frame is less a collection of fixed bays and more a platform on which components are positioned around one another.
That flexibility makes practical checking especially important. GPU body thickness, connector direction, cable bending radius, fan position, drive placement, and the space occupied by cooling hardware all interact.
The source describes a mounting system capable of accommodating a wide range of hardware when it physically fits, but it does not provide a universal clearance promise for every combination.
Ports, Colours, and Variants
By default, the DA6 is fitted with a power button and Type-C 3.0 module on the bottom panel.
There are 2 additional module locations on the top panel. They can provide an alternative location to the bottom position or be used to add ports according to the available motherboard functions.
The case therefore provides space for 3 modules in total.
RGB support is listed as no. The available colours are Chrome and Black.
Standard and XL sizes are offered. The listed identifiers are ST-DA6C for Chrome, ST-DA6B for Black, ST-DA6C-XL for Chrome XL, and ST-DA6B-XL for Black XL.
Who Is It Not For?
The DA6 is not suited to someone who wants the hardware enclosed behind conventional exterior panels. Its open-frame identity is not a minor styling detail; it is the basis of its visibility, mounting system, and cooling approach.
It is also a poor match for anyone who needs a guaranteed drive count before choosing the rest of the hardware. The official specification explicitly makes storage quantity dependent on installed components and available space.
A build must be considered as a whole rather than assembled from independent capacity figures.
Nor is it the obvious choice for a builder who wants every component to drop into a predetermined bay with little layout work. The universal brackets make the platform adaptable, but that adaptability requires decisions about the relative positions of the GPU, PSU, drives, cooling hardware, and cables.
Supported riser generation, exact clearance for individual GPU coolers, a specific cable bending radius, and a recommended power limit are officially not stated. Anyone unwilling to verify those configuration-dependent details may find the open-ended layout demanding.
The case also gives up the protected, closed-box format in exchange for direct visibility and open access to air. That is the central compact-system tradeoff here.
The DA6 does not hide the compromise; it turns it into the design.
Where to Obtain It
The official product page includes a Buy route. Its Where to Buy navigation lists Our Shop as well as Americas, Asia, Europe, and Oceania.
Specific retailer names, stock availability, and sales terms are not stated in the supplied source text. Availability should therefore be checked through the official purchasing route for the relevant region.
The Point of the DA6
The DA6 is compelling because its compact outline does not correspond to a timid hardware envelope. Calculated from its external dimensions, the standard model occupies approximately 19.9L, yet it supports a 323mm triple-slot graphics card, a CPU cooler reaching 105mm to the frame edge, radiators up to 280mm, and SFX, SFX-L, or ATX power supplies.
The XL keeps the same footprint while extending graphics-card support to 358mm.
This capability comes from a very specific choice: the case removes conventional walls and uses a 19mm stainless-steel tubular frame with movable universal brackets as the mounting platform. What it sacrifices is the certainty and protection of a closed enclosure with fixed bays.
What it gains is unusually flexible placement, an unobstructed view of the hardware, and broad access to cooling air. That is why the surprise is not merely that the DA6 is compact.
It is that so much component freedom exists inside an outline of this size.
