The housing looks great (have the white version). The delivery includes everything you need: of course the housing, a suitable Phillips screwdriver, a Y-USB cable, a protective pouch and a small installation guide - even in German.
The installation of a suitable hard drive took about 30 seconds! With your thumbnail briefly leveraged on the long side and the housing already jumps up (thanks to my pre-reviewers!). Inserted disk, cover it and pressed the small (little fiddly) screw screwed - done. So I think those were not even 30 seconds - that writing this review took much longer!
USB cable plugged in, and the PC hung (Win 7 64bit) - immediately recognized.
Top class quality: could not be better: buy recommendation!
