mini ITX Case Project 009 Micro

Micro was my very first project that I designed entirely from scratch. While it was loosely inspired by a concept from Optimum, the Nano Rig. I pushed the idea further: making it even smaller, simpler, and built without a dedicated GPU.

The case was a huge milestone for me – 3D-printed in carbon fiber with a custom anodized aluminum front plate I had produced to my own design. Power was another challenge: instead of a standard PSU, Micro runs on an external power supply paired with a Pico-style DC-ATX unit, keeping the internal volume incredibly tight.

For performance, I chose the AMD Ryzen 7 8700G – a powerful APU with strong integrated graphics, ideal for such a compact system. Cooling was solved with a Noctua NH-L9a-AM5 low-profile cooler and two tiny Noctua 40 mm fans in the front, proving that even in ultra-small form factors, airflow and stability can be maintained.

The goal was simple but ambitious: build an ultra-compact PC that still delivers excellent everyday performance. Micro achieved exactly that – and today it has found a new owner who is absolutely thrilled with the result.

Bring the iconic Project 009 – Micro to life with these downloadable 3D print files.
This ultra-compact case was completely self-designed and optimized for performance in the smallest possible footprint. With space for two 40 mm fans at the front, and a design proven in real builds, it’s the perfect project for SFF enthusiasts who want to print and assemble their own Micro PC.

The case is best printed in ABS or PETG for durability and heat resistance.
