It is interesting to note he gets extreme hip rotation into the serve (in my estimation - more than Roddick), launches his weight far into the court, and has a quick motion (no standing around in trophy pose).

We can say that being taller helps with hitting the serve hard and especially finding angles. Having good jumping ability also makes a difference. But in my personal observation on some of the rec courts of Southern California, the biggest issue is poor form.
So crazy! I agree, he gets insane rotation though. Just stupid amounts of free power.

The height thing is a factor, but not so much at the rec level IMO. Technique definitely plays a huge role in how much power you get.
