The weird thing is some do publish the price of 1U/1 Amp along with half-racks and full racks, and nothing in between - not even a formula to estimate costs if one doesn't nearly fall into one of those buckets. The 1U pricing suggests that some do care about 1U collocation, while simultaneously limiting price information to quote requests for a 2U or an 800W 1U. It's strange.
