The ICY BOX IB-319StUS2-B is a undemanding, quiet and particularly reliable worker. Undemanding: insert HDD, position ICY BOX, connect - power and USB 2.0 or eSATA. Nevertheless, if you want to change the HDD, you can do it with the PC running, just disconnect (Hot Plug & Play, Hot Swap). Quiet: the aluminium casing dissipates the heat, noisy fans aren't needed. Reliable: it's a typical ICY BOX. If you want to save power, you can even switch it off.
