How can I create a simple case?

Question

How can I create a simple case for my Raspberry Pi?

I don't need an airtight case; I'm looking for a simple and cheap case, just to be sure no one touches the circuit board.

Answer 1

The easiest and cheapest case must be The Punnet; it is a case made from cardboard. You can download a PDF, print it onto your favourite coloured cardboard, cut it out and stick it together.

Answer 2

Of course, if you have any Lego hanging around that's another easy solution.

In fact, there was an article on the front page of the Raspberry Pi homepage detailing just that: http://www.raspberrypi.org/archives/1354
