Design and features: The case is well thought out in my opinion. It is closed, except the air vents on the underside and the recesses for the corresponding ports (Ethernet, USB, etc.) It pleases me well that the notches fit exactly. So you put on a port that does not have to be feared that the connection is bent. This refers, inter alia, the connection for the Sata Power. Also you can reach including the I / O pins, if one removes the "flaps" on the top of the lid. This can be solved by gently squeezing the sides and later arrested again. In other cases, which I bought for my Raspberry Pi, an access map pins either was very difficult, or it was just an opening exists. The disadvantage I find that the board is seated close to the vents, so it does not make the impression as if you stick such as passive cooling elements on the A20.
Structure: The structure is very simple, even if the instructions possibly. Something else promises, I have less than 3 minutes to hand the case to put together. A guidance lies with the housing but also, however, this corresponds to the figure on Amazon ..
Overall, I am very satisfied. The case makes a stable and respectable impression. Since I did not want to wait 30 days I slammed here and did not regret it until now.
