Got three several months ago. One to just use as a Linux host, one to connect to my weather station and one to [hopefully not] fry with a breadboard.

FYI, out of the three cases I've bought for the Pis, I like these two the best so far: http://www.adafruit.com/products/1067 and http://www.adafruit.com/products/975 (just about indestructible and available in other colors).
