I'm currently using a MU-747 as a USB enclosure, but I was thinking about dropping the provided SATA bracket into my case and using the extension cables supplied by Bytecc. First of all, it looks like the extension cable that goes from the enclosure to the I/O panel is eSATA - is that the case? If it is, I don't understand how then that panel can be used to hook into a MB SATA port. Isn't there some sort of electrical difference between SATA and eSATA?
