I have bought three of these now for my drives that are lying around. They come with the enclosure, an esata cable and a USB cable. Also comes with a esata port adaptor that plugs into a sata port for your desktop that would go in one of the slots on the back of your computer.
With the esata connection I get write speeds of around 80-95MBps and read of just over 100MBps which is pretty fast I thought. You should also be able to just about get a 12.5mm hard drive in there as well. Cant go wrong for £5 delivered.
