The Mac mini was hidden in an expanded LEGO brick designed as a 1970s terminal.

LEGO Culture in the United States and a New Megaproject from M2x2
In the United States, LEGO bricks have become a true phenomenon. Even older people happily talk about their projects, building huge structures out of blocks. One such project – M2x2 – is a modern interpretation of a computer terminal from the LEGO Space sets released 50 years ago.

What is M2x2?
- Author: Paul Staal.
- Idea: turn a children's toy into a working desktop PC.
- Scale: the case is ten times larger than the original but retains its characteristic “brick” look.

Technical part
Component Description Main computer Mac mini with an Apple M4 processor – enough power for everyday tasks and even serious work. Case 3‑D printed on a printer (model created in Fusion 360). Uses heat inserts, screws, and glue. Cost of printed parts is just over $100 (excluding the Mac mini itself). Open schematic Files and instructions are available for free; any enthusiast can build the device on their own 3‑D printer.

Conveniences and additional features
- External display: a 7‑inch screen mounted on an angled panel, functioning as a second monitor. Often used for Home Assistant – displaying smart home data and the status of a 3‑D printer.

- Hidden gadgets:
- IKEA Symfonisk remote (music control).
- Wireless charging module for AirPods or Apple Watch.

Thus, the exterior remains an identifiable “brick,” while inside it is a fully functional computer.

Conclusion
M2x2 demonstrates how to combine retro LEGO style with modern computing power and useful gadgets. The project is open to everyone: files, schematics, and instructions are free, allowing anyone to build their own “LEGO‑PC” on a home 3‑D printer.
