Heres my first arduino youtube video. its a good one. I made a housing for my arduino out of an old power supply case for a computer it has two fans for cooling built in. I also put a red led between the arduino's 5 volt and ground pins to indicate that its powered up. Arduino Uno project. - YouTube
Well done!
young engineer of the future.
Surely in the future you will be an old engineer. 
Wow, with all that fan cooling you might be able to overclock that sucker to run at 1Ghz.
