The set is really very good, and the conversion of the computer is very easy. However, missing at least for me a detailed description of the conversion. It is therefore advised in any case, beforehand to search the net a good video tutorial and to proceed according to this. But then everything works out very well and the frame fits perfectly. Installation of the optical drive in the new external frame is relatively simple, but here is the lack of detailed description to pay close attention to what you are doing. The breaking out of the corresponding nipple was relatively difficult without tools. Here you have to know how to help, because the instructions can be a rather alone. Another minus point is the enclosed tool for unscrewing the screws are not really suitable. I turn with my own screws more success. So overall a good thing, but with small drawbacks. For a star deduction.
