I really like my Pi Box... In fact when the 512meg model came out I bought another Pi Box as well (this time from Newark because it was easier to find them in stock!). However I recently tried to see if one of Adafruits 2.2" LCDs would fit in the case. It just barely doesn't... however the real issue was that like a number of other posters I broke a claw off. The odd thing is that I recall the case being much more durable when I put it together originally. I was very careful both times, but taking it apart today it just broke. It almost feels like the plastic got brittle extremely quickly... it felt like the plastic in my car that is 15 years old
I did get my Pi out of the first batch but that was just earlier this year. I love the case, but I wish there was a way to make it a little stronger. I wonder if a slightly different acrylic could be found to make this stand up a bit better.
P.S. I'd love tiny display that fit in the case or a slightly bigger case that could take a display
