Hi XYZ
is the way to go. The first letter of a sentence should be capitalized. Even in the most informal settings, lack of sentence case smacks of laziness. Whether the sentence in question is "Colorless green ideas sleep furiously" or a simple "Hi Joe", doesn't matter.
I think the capitalization is important. However, there are some settings where a "hi xyz" is acceptable---namely, when the entire email is in lower case (as is often the case when sys admins and other hacker-friendly people write emails).
But, despite that, I think it would be unwise to use a lower-case "hi" in a handwritten or printed letter (though in these two forms of letters, I would rather prefer using "Dear XYZ" instead of "Hi XYZ").
