This is my XFCE setup. I like clean layouts and dark themes. XFCE is extremely customizable and snappy and I always come back to it.
Even though I don't like Windows very much, I do like the clean square lines in the UI. That's why I have used the Windows 10 theme here.

The result is a minimal desktop, easy on the eyes.
