Help w/ Wooden Wall Finish

One wall in my apartment will have a lot of holes in the drywall once the built-in shelves are removed. I want to cover the wall with treated wooden planks to look like the picture above. How would I go about doing this? Should I use wide flooring planks or will any ole planks from Lowes (stained & treated) work? Should I rent a nail gun and just nail them to the wall? Am I crazy to attempt this DYI? Any suggestions or hints welcome. Thanks!
