And this one.

Reasons are that I think that it is a bad idea to use multiple different 
indentation levels when there is no nesting going on.

While you could decide to align the case with the when and else in the 
last one I feel that it stands out better this way without obfuscating 
start or end. With this you can also do this:

speed = case direction
   when :left then -5
   else +5
end

But having options is a good choice for restyling tools.
