Concept Odesce Studio – Project Hexa (Hexa v1)

[Deodesce]

Hi everyone,

I’d like to introduce a project I’ve been working on for the past few months.

Odesce Studio – Project Hexa (Hexa v1) is a modular / expandable small form factor (SFF) case concept that is currently in early development. The goal is to explore whether a single SFF enclosure can adapt to a wide range of hardware configurations through controlled expansion.

I am currently working with a manufacturing company and their design team, but the process is still early and evolving. Before moving further into detailed CAD and prototyping, I wanted to share the concept here and gather feedback from the community.

Concept Overview​

The core idea behind Project Hexa is a case that can expand in three dimensions:

• Length (X-axis): to support different GPU sizes
• Width (Y-axis): to accommodate larger radiators and cooling setups
• Height (Z-axis): to enable multi-radiator configurations

The intention is to maintain a compact footprint when unextended, while allowing flexibility for more demanding builds when expanded.

Current Estimated Dimensions​

Compact (Unextended):

• 340mm (L) × 149mm (W) × 238mm (H)
• ~12.0L volume (estimated)

Fully Extended:

• 410mm (L) × 179mm (W) × 298mm (H)
• ~21.9L volume (estimated)

Target Hardware Support​

• Mini-ITX motherboard
• SFX / SFX-L PSU
• Expandable GPU compatibility (length and positioning)
• Custom water cooling focus
• Dual radiator support (clearance ~66mm, still under evaluation)
• Side-mounted fan/radiator support (140mm / 240mm, possibly 360mm in extended mode)

Large air CPU coolers are likely not a priority due to layout constraints.

Internal Structure (Chamber Design)​

The design is currently based on a 3-part structure:

• Chamber A (Front): intake area with front fan support
• Chamber B (Rear): motherboard I/O, GPU mounting, and optional glass side panel
• Chamber C (Core Structure): internal frame that connects A and B

Chamber C is intended to act as the structural backbone, maintaining rigidity while allowing controlled expansion in all three axes. It also serves as the mounting structure for key components (GPU, PSU, radiators, etc.).

This area is still under heavy development, especially in terms of mechanical design and how the expansion system will be implemented.

Layout Flexibility​

The design aims to allow flexible component placement depending on configuration:

• GPU positioning may vary (side / top / bottom depending on setup)
• Radiator placement can shift based on expansion and clearance
• In tighter configurations, GPU position may be adjusted to improve radiator clearance

There is also an adjustable rear I/O support structure to account for changes in layout and clearance.

Additional Features (Planned)​

• Hidden power button and USB-C port
• Optional glass panel (Chamber B side)
• Bottom airflow support with dedicated feet design
• Potential handle integration

Current Challenges / Concerns​

• Designing a reliable and rigid expansion mechanism across 3 axes
• Airflow optimization with multiple radiator configurations
• Rear panel design when accommodating varying GPU sizes
• Radiator clearance limitations (~66mm may be restrictive)
• Overall complexity vs manufacturability

Notes​

This is still an early concept and many aspects are incomplete or subject to change. I’ve spent a few months working on the idea, but I’m aware there are likely significant design challenges ahead.

I’m open to direct and critical feedback—especially on the overall concept, mechanical feasibility, and whether this approach makes sense within the SFF space.

Thanks in advance.

Additional Notes​

• I am currently looking to collaborate with someone who has strong mechanical design experience, particularly in areas like structural systems and movable/expandable mechanisms. The concept has reached a point where proper engineering input would be extremely valuable.
• The different colors shown in the images are only for visualization purposes, to better distinguish components and structure. They do not represent final product colors or finishes.

I'm an air cooler enjoyer so this isn't something I would purchase, but it's a cool idea and I hope it works out for you.

That’s actually something I’ve been thinking about too — it’s been challenging to make the front fan work as the main airflow path. I agree air cooling is preferred by a lot of people. Hopefully the final design still catches your interest, and thanks for the kind words!

Hey there, great concept overall. I look forward for more updates!

It seems that the image is not being attached properly. In case you encounter an issue, probably you can try these steps https://smallformfactor.net/forum/threads/how-to-upload-post-image-in-the-forum-using-imgur.15817/

Thanks, appreciate it! I’ll update the image links once I get the chance.
