I like this nifty, 3D printed Arduino case that I saw on Shapeways:

IHeartEngineering says:

This is a modular case for the Arduino Microcontroller. It has been designed to fit 6 across in a 1U Rack with a little room to spare. M3 Screws are suggested and not included. The holes have not been drilled or tapped, so you can use #4-40 screws as well.

You can have one made in a variety of materials with prices starting at $77.71. Now, that seems pretty expensive for a project case, but I imagine it’s much cheaper than having an injection mold made.

I like the rounded corners, in fact I’m jealous of them. Since I tend to make stuff for laser cut construction there are certain unavoidable 90 degree angles. Unless I bust out a router or get crazy with the sandpaper.
