I have to wonder what the goal here is. If its to kill the character, then just kill him - have someone slit his throat in the night or use a big junker gun or whatever. The player will be annoyed regardless and will just make another character in the same way - trying to min-max the physical stuff.
If you want to show the player the weaknesses inherent in this type of min maxing, you need to force the character to use his weaker abilities. Hit the guy with situations that require Mein or Cognition tests - or whatever he is weak in. Send the party on a mystery solving adventure that has very little fighting in it, but relies on the often unused attributes. Find situations where other Edges would have been handy.
Don't get into a "mine is bigger than yours" fight - all you'll do is prove the player right in his own mind.
