The case is solid. The Raspberry Pi + B / 2 locks onto the body. Clearance for a heat sink (if fitted) is also available. The shape is not a design classic will come of it, but functionally it is very well thought out ONLY the rejuvenation of the housing at the end (when the end of the opposite side of the narrow starts with the USB ports and LAN port) makes problems when using eg the data cable as it comes with the starter or SunFounder sensor kit. The connection of the cable is too large, or the rejuvenation of the case makes it impossible to close the case with an attached cable.
