Actually, it's annoying to need a box for a desktop nowadays. But the trend towards ventilated cases makes it a necessity - there's no protection against the elements.
Heck, I have problem with mine sitting near the door after I come in from the snow.
Not really - most other desktop cases are much flimsier and don't come with as well designed packaging. I've had computers not POST after shipping because something was dislodged in transit, but that never happens with the Mac Pro.
