Never used, excellent solution for making a SATA hard disk external.
Comes with both USB and eSATA connectors on the back.
Fully boxed with UK power supply, screws, manual, pre-Windows 2000 drivers (it installs automatically for Windows 2000 and above) and even a screwdriver to put it all together!
The enclosure body is silver metal with a light blue plastic bit on the front where the status indicator is.
EDIT: Sorry, the front of the enclosure is actually black, not blue as stated in the description and shown in the picture.
