Not sure if its the same with your pre-built waterblock systems. But I believe the same applies imho.
Hum mine came fully sealed so there was no way of getting air out, and I suppose if the air was removed you would either have to instill more coolant or have a vacuum. When you think about it it does make sense to have a little air to allow for expansion.
