This seems to have been posted in the wrong place...
Anyhow, the screenshot is hosted by WoWInterface.com so therefore it's likely that the UI you are looking for exists somewhere on this site. (can't help thinking that I've seen this UI before, but what the heck, they all look the same.. )
Best bet for you is to look through the various ones in this download category.
