No, but you can write easily an emacs command to do that.

(defun beautify-case-braces ()
  (interactive)
  (beginning-of-buffer)
  (while (re-search-forward "\\<\\(case .*:\\|default[ \t\n]*:\\)[ \t\n]*{" nil 
t)
     (let ((case-text (buffer-substring (match-beginning 1) (match-end 1))))
       (delete-region (match-beginning 0) (match-end 0))
       (insert case-text " {"))))
