When I heard about the Raspberry Pi being released, I preordered waaaaay to many. My house has two for XBMC and a third for a side project. I gave one away and used the last here at work. People ask quite a few questions when they see it, so here is the setup.
Our Pi is just browsing two websites, Cacti's weathermap and Nagvis's picture- hostesd off the Nagios server.
Raspberry Pi Model B 512MB
4GB SD card
Any 1080p TV of your choice
It's low power and small footprint make it ideal for this task. I'm hoping to move our kitchen computer over too.
Let me know if you have any questions!
