The aim of the case was to fit it under my TV as Proxmox/NAS/Home assistant/Second gaming PC inside Ikea Kallax compartment. I wanted to use leftover GTX 1070 + have system fully passive so NH-D14 with single fan had to fit there (I haven't found any other ITX case that allows that) - system operates without spinning fans under idle load below 55°C on my Ryzen 3600x using Gigabyte Aorus B550i Pro AX. I used be quiet! 600W SFX-L and everything fits nicely.
I think you can even fit RTX 4090 into it as I provided enough space - making it smallest and most powerful 3D printed case IN THE WORLD.
