Yes for the SM580, and for the SM570 it depends on the final design (if the bottom fans are removed it might not be big enough to justify wanting a handle)
I'm kind of leaning the same way. The SM580 sounds great for a double radiator build where the heft would require a handle, but depending on the 570 layout, it might not need one. I'm still in the air about all of the new exciting cases and what will actually be required to keep the Zen2 thermals in check.
Either way, I think that the prices for the 570/580 with handle are both reasonable.
