First off, when it's together you will notice that its tough and gives a nice amount of weight to the raspberry pi, but not too much that it removes the portability from the little thing. It's packaged well without much extra unneeded packing, but the protective film on each piece is almost impossible to remove! You have to scratch a groove into it so you can peel it off, as long as you dont scratch the acrylic! It is well vented too, and has enough space for heatsinks etc., and even overclocked it doesnt get too hot! I havent tried it without the heatsink, but I'm sure it wouldnt be too warm.
