Description
This project was created with the idea of building PC in a compact form but using standard ATX hardware. It is dedicated to All in One water cooling systems and supports popular formats such as 360 / 420mm. Triangulus ATX Tower is an impressive open-air case that surprises with its form and functionality. It accommodates standard computer components while taking up significantly less desk space than a typical computer case.
The Triangulus ATX Tower is inspired by my previous design, the Triangulus ITX Tower, but has been completely redesigned to meet new requirements. It offers functionality not found in the previous model, allowing you to build a computer with standard ATX hardware. To enjoy this design, you don't need expensive ITX/SFX components.
Hardware Compatibility
* With SFX to ATX adapter: Link
** tested with MSI RTX 3070 Ventus x3 ~1Kg, to mount 3-slot GPU use optional x3 GPU Bracket
Printing
For maximum durability, print with ABS in a closed chamber.
Basic parameters
- nozzle 0.4

GPU Beam, GPU Bracket and PCI-E Riser Bracket print with 4 wall count for better stability.
To avoid warping on large parts, clean the work surface with dish soap. Using an adhesive glue is a good idea.
