This was a custom overlay I had made using the art from League of Legends Hexakill Mode (I loved the theme)
The Top bar is a slim overlay that I use to put info on like Mail, LFG button etc.
Dependent on Sunnart - Viewport Art Addon (This is overlay art, not a full UI setup)
Great Addons to use with this is moveanything, bartender4 and Opie
Follow me on twitch.tv/nerkcast as well for future artwork and games
