Free three columns blogger template : KleenGreen

This template is similar to the template Kleen. I just changed the header image from the Header Edit button, and changed all the fonts and colors from the Fonts and Colors in the Layout page just to show that you can customize a lot even without tweaking with the HTML code.
Note: Remember to upload a header image with 950 by 150 pixel size and fill up the Linkbar when you use the template. Otherwise, your Header will be cut off.
