HOT Raspberry Pi DIY Mini Desktop PC Build
Observations and Conclusion
That said, of course the Raspberry Pi can also be overclocked (to around 1GHz core, 500MHz RAM, 275MHz graphics) to its highest setting for Quake and the like, and still not go over its thermal limitations, given proper airflow. As you'll note, we have a small heatsink mounted to the main processor on board, which did help moderate temps nicely.
Though this little machine isn't going to break any land-speed records or give IBM's Watson a run for its money, our efforts with the Raspberry Pi were spent out of the love of technology and creativity. There are a number of practical uses you could imagine with a little machine like this, especially as a field device for quick monitoring and diagnostic functions, but we just had fun building our own <HOT> Raspberry Pi.
