all 3 components have been delivered. the installation of the Raspberry Platikgehäuse was seamless. Just be aware with the micro SD memory cards when you switch - wenns goes wrong, you have to shake out from the housing again. The Raspberry Pi works with the power supply problem. You just have to be careful with the operating systems of wegem Raspberry Pi2 support. I have been playing for the Raspbian Pi2 and Retropie 2.6 on one memory card, both booted correctly and Retropie 2.6 makes a lot of joy, because I bought the Raspberry Pi2 precisely for this purpose.
