If you use 12mm or 14mm with boxed spokes, use an ERD that aims for the screwdriver flat of the nipple when calculating spoke length.
If you use 16mm with boxed spokes (which I don't really like) use an ERD that aims 1-1.5mm below the screwdriver flat of the nipple.
...else you run the risk of running out of threads before proper tension has been achieved.
10mm nipples if usable with this rim give you a lot more overhead - aim somewhere between the flat and top in that case.
For 16mm nipples, its a lot easier if you hit an LBS with a Phil Wood spoke machine...assuming they know how to do the 12mm threading operation they can eliminate the need to short the spokes with 16mm nipples.

1. I do not claim to be an expert in bicycle mechanics despite my experience.
2. I like anyone will comment in other areas.
3. I do not own the preexisting concepts of DISH and ERD.
4. I will provide information as I always have to others that I believe will help them protect themselves from unscrupulous mechanics.
5. My all time favorite book is:
Kahane, Howard. Logic and Contemporary Rhetoric: The Use of Reason in Everyday Life
