I bought this case for a colleague who needed an external hard drive for his MacBook. Because it makes more sense in my opinion, to buy a good housing and to a selected "internal" hard drive, I opted for this housing. He did not require high speeds and so USB 2.0 was absolutely sufficient. Enermax may be more expensive than many of its competitors, in my view obstructed but the best and most reliable controller. Unfortunately Enermax that "building system" something has changed compared to its predecessor, so I subtract a star. In the previous one needed no screws. The cover, which was provided, moreover, with many vents (this does not) was just put on and then slid into a holder. Here you have this cover with 4 small screws (or 2 if you only change the hard drive will) fix. If no doomsday, however, was how to find previously elegant and comfortable solved primarily.
