CC 003 Tryx - Open Air SFF PC Chassis

An updated 2.0 version of this chassis is in the works! I would advise waiting for the update if you want to print this. See the bottom of the description for more info on what's to come in the updated model.

This chassis was designed specifically for the MakerWorld × TRYX Open-frame Case Design Contest.
 

While this is an SFF, open-air chassis specifically created to showcase the TRYX Panorama ARGB SE CPU cooler, I aimed to develop a versatile model with a strong focus on ease of assembly and simplicity in design.
 

Unlike many other open-air PC chassis, this design features deliberate and precise cable management with zero compromise, allowing key components to remain in the spotlight—exactly as an open-air system is intended to do. The inverted power supply shroud channels cables directly into the stem of the chassis, keeping them completely hidden before they are neatly dispersed to their respective components. The shroud also includes an integrated, bottom-facing velcro channel and a dedicated cable pass-through, ensuring the AC power cord is properly managed.
 

The stem and base house an additional eight Velcro channels (three bottom, two right, three left) to securely route both cables and the CPU cooler tubing. To simplify cable routing, the areas surrounding the 8-pin EPS and 24-pin ATX motherboard connectors have been kept relatively open, and a dedicated, enlarged cable pass-through is positioned behind the GPU. Display, power, and peripheral cables can exit the chassis from the bottom-left, further reducing visible cable clutter on your desk.
 

The chassis also includes a highly compact GPU mounting solution. Unlike traditional chassis designs, the GPU is not secured using standard PCIe bracket screws. Instead, the base of the PCIe bracket is clamped directly to the top of the stem. This eliminates the need for bulky standardised mounting hardware and reduces material usage, while maintaining sufficient rigidity. The GPU attachment is compatible with all GPUs using standard PCIe brackets.

Key Features include:

• Enclosed stem equipped with velcro-channels for clutter-free and user-friendly cable management
• Seamless 3-piece design for an open PC assembly environment (base-stem-topper)
• Enclosed PSU shroud with integrated velcro channel for power cable
• Top and bottom pass-throughs for display, peripheral, and power cables
• Novel GPU PCIe bracket for compact yet rigid assembly
• Reinforced geometry with sturdy attachments to accommodate heavier components (motherboard, PSU, GPU, radiator/fans)
• Magnetic and poka-yoke interfaces for easy assembly of the chassis
• Integrated tool-less assembly for a “standardised” power button
• TPU-padded base for added vibration dampening
• Top-facing motherboard and GPU I/O for added convenience
   

Please refer to the attached assembly manual for further details.
 

While it remains untested, I advise against using materials with an HDT lower than PETG (~70 °C) due to thermal requirements. My recommendation is to use PETG CF for added rigidity (or ABS, ASA, PC, PA if your printer allows it).
 

Designing this has been an absolute blast. The only thing I regret is not starting sooner—there are several details I would have liked to refine further if time had allowed. I may continue finalising and iterating on the design after the Christmas break. In the meantime, enjoy—and feel free to reach out if you have any questions, concerns, or feedback regarding the design.

Disclaimer!
This design has not been tested and verified with a full set of genuine PC components.

My future plans for this design:

• Fully fledged testing with a genuine PC setup (assembly, stability, feel, performance, cable management)
• Further refined construction, design, and hardware selection
• Optimised print profile for quality and efficiency
• Support for SFX-L power supplies
• Potential support for longer graphics cards
• Improved assembly guide
• Material exploration and viability
