I bought the housing and the cooling elements together with a Raspberry Pi Model B 2. I'm not very proficient in electronics tinkering - therefore a short guide for me would have been very helpful, as the delivered parts are to block. I must admit though that the actual housing assembly is also largely self-explanatory. If you look at the pieces of the puzzle in peace, you will find out sooner or later and even where the 4 small screws must be mounted with the enclosed disposable screwdriver. Right away I had not realized that in the 4 (very accurately positioned) fasteners are threaded so that you can screw it to the housing base the board. Here helped Trial and error for Use Find out your patience for fiddly work and the necessary courage and the screws as far as to tighten up the board no longer shook. Now the heatsink came off: the quotas for the large and one of the two small heatsink were obvious, so the paper from the adhesive deducted at the foot of each heat sink, the two positioned and pressed briefly. Ready's it and held well. Just what to do with the 3rd heat sink, I did not realize. So the omniscient Google asked: the answer was a little unclear, but I have understood mean that the third heat sink is simply not needed with my Raspberry model. So I left him. As an enclosed note would be useful, whither which heatsink is or in which Raspberry model on how to proceed. Then the housing cover has to conclude clicked on the housing floor and the mini-computer was packed and ready! The processing of the case is good, the mounts fit exactly to the holes in the board. At the interfaces are recesses, so you zoom thereto comes good with closed housing and on the bottom there are vents. The two housing halves can be combined well and reopen if necessary. Included are 4 screws for mounting the board, a screwdriver for those screws and 4 small adhesive plastic feet for the housing. The 3 heat sink (1 large, 2 small) are provided with adhesive on the bottom, so they were easy to assemble. Only 1 star deduction for the missing description. Something should be included in my opinion - it rich really a sketch and a brief note on the placement of the heatsink.
