I'm still waiting for delivery of my Pi, so have been looking at case options again. Here are some more that look quite interesting, the PiBow, PiWorks and Bramble Pi
Some exciting news I've just read is that the popular phone operating system; Android has been successfully ported to the Raspberry Pi.
As well as the choice of case there are a number of options for operating system for the Raspberry Pi.
Without getting too technical, the Pi has an ARM based processor so will only run an ARM compatible operating system. Both Windows (up to windows 7) and Mac OS X run on x86 based processors so are not compatible with the Pi. The main operating system that the Pi will run would be Linux.
One of the most important choices while I wait for my Pi to arrive is what case to put it in. The case will not only stop the Pi getting damaged and dusty it will also make it look good.
Searching on the internet and looking on the official Raspberry Pi site and their forums, there are all sorts of cases available. Made from everything from Lego and paper to metal, plastic and wood.
