So what happened with the first Raspberry pi? Well I sold it to a colleague of mine.
Unfortunately by selling all required elements of my first working Raspberry pi setup, I had no HDMI cable left to configure the second.
So while waiting for the HDMI cable, I also ordered one of the plexi enclosures for the raspberry pi designed by adafuit on ebay.
Voila, here's my setup:
What's next? I'll try to setup a NAS with this raspberry pi, a self powered USB hub and some external USB hard drives. (If I find a few minutes of spare time :-) )
