This housing for the Raspberry Pi B + is something for hobbyists among us. Because it comes in pieces like an Ikea shelf. But without Allen! It makes a good impression if you have it once composed and a bit has tuned. First you should get a plastic adhesive. I have used by Revell, because it is very easy to dose and was just at hand. Before the parts are joined, the cutout for the power supply should be made slightly larger, as most plug that I have tried, not sure sitting in the connector, since the neck is held a little too tight. So, now you can build the housing together. This is very good and the parts fit together very well. I recommend, however, to put the case together only once a trial basis. Now, if you know how everything belongs together, you can go to the final assembly. This one should remove the protective film from all parts. Because actually the case is crystal clear, however, what one does not see in the delivery condition, since the protective film lets the whole thing seem a little dull. Now you put the pieces together again. The board should already be used with, as they hardly can be used after assembly. If then put all the pieces together and sitting all in place, you should fill out with the craft glue all joints, thus making the case only really stable. This is recommended therefore, since the plate on the USB ports side by the rather large cuttings is relatively unstable and easily broken. In addition, the housing without bonding is a bit shaky. The accompanying heat sinks are a good accessory and should be used in any case. To improve cooling, the aufklappare top is always open during operation with me All in all, the housing through the crystal clear material looks good. Although it requires a little tinkering, so it is a stable housing after bonding and also looks good. I highly recommend it!
