Some real pics of my Pi
If you read my about page you saw that my Pi had no case. That's why I made one by myself.
The price of the cheapest Pi case is somewhere around 10$. It's not expensive at all, but since I had some old LEGO in my house and since I am a more DIY type than a money thrower and the LEGO was sitting in a drawer doing nothing but eating space, I made a case out of the LEGO pieces that I had found.
