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 " {"))))
