The housings are perfectly finished and look good doing it from (piano finish ...!). The S-ATA connector fits perfectly, there was none of the 3 housing, which I bought, any problem. All built-in drives work properly with the USB cable supplied, respectively, so that no additional power supply is required. And that's just fine! Quite apart from this was also supplied each a "mini screwdriver," with the S-ATA connector can be screwed into the housing ... All the best!
