I had this unit for around 8 months and had only used it about a dozen times. There is nothing wrong with the unit cosmetically and functionally. I am selling this simply because I rarely have more than 2 drives simultaneously in the bay therefore I decided to just go for 2 HDD caddy. It will come with power supply and esata/usb 2.0 cables.
