Superb, good finish. The radiators for the graphics chip and processor attaches smoothly. The advantage is that the top cover can be opened without having to disassemble it. The installation video provided in connection is good (B version, but it's ditto). Just a bémole which has no relation to the quality of the product, plexiglasse protective plastic films are hard to remove. But at least as we receive it it is all clean once mounted nickel. Small photo montage finished :)
