I just got mine and was immediately disappointed with the cheap quality. The eSATA connector is mis-aligned and will not work. The power supply is weak and has trouble spinning up a 4 platter 400GB drive consistently. After one hour of use I pulled the drive out to check on the heat and it was way too hot. I work for a drive manufacturer and can guarantee a shortened life for any drive running inside this box. The case is aluminum but there is no conductive path to pull the heat from the drive to the case. It also has a solid metal cover over the circuit board that holds in more heat. Don't even think of wasting your money on this!
