Interestingly, case manufacturer listed CPU clearance is not always valid. I think they are usually very conservative.
The Antec One
lists a max CPU cooler height of 155mm.
The Hyper 212 PLUS at 159mm fits with ~3mm to spare, disregarding the bulge on the side panel.
However, I'd go with what they say, unless you see actual installations of the exact parts that show otherwise.
