Raspberry Pi computers are, of course, loved by experimenters, hackers, and makers worldwide. Their bare bones design, without an enclosure of any sort, helps keep the cost down, while encouraging people to experiment with how they work.
Unfortunately, this become a liability in some situations. You’d rather not expose all of these parts to, say, a kindergarten class. On the other end of the spectrum, placing one in an establishment or home among people that don’t appreciate the bare hardware aesthetic will be less-than-appreciated, even if it does its job well.
You could design your own enclosure, which is a lot of fun for some people, but if you’d rather concentrate on programming, you might consider the Raspberry Frame Oak 16 from Chk-creative. The front panel houses a 7″ touchscreen display, while the Pi that powers it is hidden behind an aluminum grate. Looks like a great setup for a streaming device or informational display that would fit in with, for example, a well-equipped kitchen!
Along these same lines, if you’d like a classy place for your RPi, but don’t need a screen, this simple oak case from the same source could fill that need nicely.
