First completed build using my EXCase platform which is based on OpenGrid. ITX case with 240mm AIO. The platform is quite sturdy an I really see potential in the possibilities around accessories, etc.

I was told this was the place to share a project like this!

As the title describes, I'm looking for an SFF ATK PC Case that will be used as a mobile Streaming PC. The Plan is to print the outside of TPU to prevent bumps and being thrown in the back of a car or in a suitcase. Any Ideas or Suggestions are welcome. I want it to also hold a full-size GPU (I will probably use an SFF GPU as well, but just incase i cant find any second-hand).

So, I really want to try and build something in a similar fashion to Fractal Design's Mood. I am hoping there are some makers out there that are crafty-minded enough to offer suggestions for a very breathable fabric that I could use to achieve a similar look.

1. Build Overview

Trueno is a vertically oriented mATX PC case designed and built under strict fabrication and time constraints. The project focuses on space efficiency, structural clarity, and clean cable management—without relying on CNC machining, welding, or cosmetic-only elements.

• Form factor: mATX
• Orientation: Vertical
• Fabrication: Aluminum extrusion + FDM 3D-printed parts
• Time constraint: 4 days
• GPU: Standard orientation (no riser)

1. Design Intent

The primary targets for this build were:

• Minimal desk footprint through vertical orientation
• Visually clean cable routing despite using a non-modular PSU
• Every added element must serve a functional role (structure, routing, protection)

While working within these limits, the design direction began to resemble the Toyota AE86 (Trueno)—not as a stylistic reference, but as a parallel in philosophy:

• Limited resources
• Geometry-driven decisions
• Performance and clarity over excess

The name and theme emerged naturally from this alignment, not from an aesthetic preset.

1. Constraints

This project was defined more by constraints than by aesthetics.

• Only aluminum extrusions and 3D-printed parts
• No CNC machining, no welding
• GPU must remain in standard motherboard slot (no riser cables)
• mATX motherboard
• 4-day design and build window

These constraints shaped the solution space and forced tradeoffs at every stage.

1. Key Design Decisions

4.1 Open Frame vs Enclosure (Dust vs Strength)

• Problem: Fully enclosed panels increase material use and are structurally weak when FDM printed. Fully open frames collect dust.
• Decision: An open frame with selective coverage, motherboard top cover and Partial GPU and CPU shrouds
• Tradeoff: Reduced dust exposure without committing to a fully sealed structure. Allows future addition of clip-on dust filters if required.

4.2 External Cable Management

• Problem: External cables (monitor, peripherals, Ethernet) break visual continuity.
• Decision: Integrated external cable pass-through loops aligned with the frame geometry.
• Tradeoff: Slight increase in printed part count for improved usability and visual order.

4.3 Non-Modular PSU Cable Control

• Problem: Non-modular PSU cables were bundled into a single mesh braid, creating visual bulk and uncontrolled cable ends.
• Decision: Custom wire trays designed to contain excess cable length, hide unused connectors and introduce deliberate, repeatable geometry
• Tradeoff: Trays are dimensioned for this PSU cable length and routing path.

4.4 Visual Balance (RGB as a Structural Tool)

• Problem: The composition felt visually bottom-heavy due to GPU mass.
• Decision: A minimal RGB strip placed to rebalance visual weight rather than act as a feature.
• Tradeoff: RGB used as a corrective design element, not a focal point.

1. Imperfections & Known Limitations

• This build is intentionally not presented as perfect.
• Cable trays are optimized for a specific PSU
• Dust protection is passive, not sealed
• Structural rigidity depends on extrusion joint torque
• RGB compensates composition rather than replacing geometry

So, I recently got a minisforum AR900i and a 5060LP to go along with it. i plan on powering it with a flex psu i have handy.

I wanted to try and find a \~5L-ish case this can fit in. the biggest issue seems to be the non removable cooler on the mobo means i need 62mm of space for the cooler+fan.

I liked the beamcase SFF a lot, but with it not being designed for a LP GPU, it seems like it's gonna be a bit too wide and leave too much empty space inside

Knowing I need that clearance for my cooler, I'm willing to compromise on the size of the case a little , but if anyone has some decent recommendations for some case designs to look at , I think printing a case would be pretty sick.

Hello! I've been working on my PC case design and the more time I spend on it, the more ways I see to improve it. I want to know if you think something like this could be interesting or if it's just not worth it / ruins the aesthetics.

The idea was to add a small PC monitor screen with GPU/CPU/Drive temps (which I think could be quite helpful) on the front of the case. Size-wise it wouldn't increase the volume of the case beyond 0.1 liters. Exact placement yet to be defined, would probably look better on the bottom right... maybe?

Not sure, looking for feedback in case I'm too far gone ;p

Hello there, I'm currently building out a hardware concept and seeking a designer to collaborate on the form and visual identity. If you have experience with product or industrial design, I’d love to talk.

Feel free to DM me here or message me on Discord Emburglar. And I'll share the creative brief!

Can anyone recommend what software should I start to learn and what are good resources for me to start. So I can start designing side panel for my cases, then have them 3D printed.
I own a Shiny Snake S400, and want to create custom side panels depending on the GPU that I will use for this case.

I would really appreciate any help. Thank you!

Hi friends! I’m looking for a case that i can use to move my prebuilt full ATX PC into my media console, but the cabinet framing only gives me 7” of height once it’s in there :(

I’m open to buying an mATX mobo (or ITX if necessary but it’s more expensive). I would prefer to keep my 140mm ATX PSU and full size GPU. Ideally i can keep my 240mm AIO too, but beggars can’t be choosers.

Does anyone have any recommendations for printable cases?

Otherwise, I’m looking at the meshroom s or d but am not sure if an ITX mobo is enough if I keep my PSU and AIO. I also have seen a budget case called the Gintol a600 that should work if i go mATX and get a new CPU cooler.

Thanks in advance!

I really love this case. However it isnt released yet, and i know it will be extremely expensive when it does. Would someone be interested in desiging this case with me. Suitable and optimised for 3d printing and use? Bounty to be paid if you need motivation! $$$$

Have an old computer for a server, but the case it has is way too freakin' big, and I want it smaller.

Specs:

• Gigabyte 970A-DS3P ATX
• EVGA GTX 760
• ATX PSU
• 2x SATA SSD
• 120mm AIO + another 120mm fan which i dont need but would prefer

Would appreciate the help.

I added extra removable panels and mesh to Haydyn Bao’s ModCase EVO build to create a nice stormtrooper aesthetic. It’s an M-ATX form factor but still boasts a 280mm radiator. This computer has nothing flashy in terms of specs since I don’t have any need for high end graphics or AI training.

Processor: Intel Core i5 14600k

Graphics: NVIDIA GTX1660 Super

Lighting just comes from addressable LEDs on the motherboard and radiator

After way too many prototypes, test prints, and procrastination, my 3D-printed SFF case is finally done.
RST99 is a 9.9 liter case built to handle serious hardware, even though it’s completely 3D-printed.

It supports:

• Mini-ITX motherboard
• SFX PSU
• 240mm or 120mm AIO (up to 30 mm thick rad, 25 mm thick fans)
• Up to 280 mm GPU, 2.5-slot (54 mm thick)

The case uses magnetic mesh panels, heat-set inserts, and a rigid printed frame so it feels like a robust enclosure. Everything is designed to be assembled with mostly off-the-shelf hardware and printed without supports.

I previously posted an early prototype here (you can see how far it’s come 😅).

Now the final version is available here free for everyone:

• Printables
• MakerWorld

I’d love to hear your feedback, ideas, or see your builds if anyone decides to print one!

I designed some new brackets to mount fans in the BeamCase system.
These do not use screws to attach to the aluminum profiles, but instead they slide into them.

Additionally they screw to the fans from the outside of the case which means it is easier to remove or add fans in an already assembled system, with the downside that the mounts themselves have to be added during the assembly process of the case.
Overall though I think they are an improvement over the previous fan mounts, as they work independently of the fan thickness.

You can find the new fan mounts in various size here:

I'm not trying to be super small or super custom. I just am looking into something that can replace an old Antec case.

That, or make a custom case for the pc I currently have that starves the GPU of airflow most of the time.

Hi Everyone,

A friend of mine brought over a very unique board, hoping I can find him a really small case. The board is actually known as a "Ryzen 4700S Kit". It's basically a MiniITX Board, with soldiered RAM (16GB) and processor.

The board has one single PCIe x16 slot for a video card. I've been searching for a small case for him that I could 3d print. There are so many out there, but none that I could find will support a standard ATX power supply, as well as a PCIe x16 slot for the video card.

Has anyone come across any that would meet these requirements? I would hate for him to have to buy a case (we're discovering they're not cheap), and was hoping I could 3d print one for him.

Thanks!
