I use the housing together with the "Western Digital Green 3TB WD30EZRX internal hard drive (8.9 cm (3.5 inch), 5400 rpm, 2ms, 64MB cache, SATA III)". It cools well, it turns automatically to standby, the access speed is very good and it looks visually from simple. I have 2 more housing in operation and can say that this case with one of my favorites.
