That seems unnecessary. I'm merely quoting the specifics for both products. Sometimes these will take into consideration things like a side panel fan, or just allow extra clearance for no real reason.
In this instance, the Hyper 212 Evo is listed as 159mm tall, the Hyper 212 Plus is 158.5mm and the Antec One officially allows 155mm of clearance.
I'm not saying there is no way it will fit, in fact it would seem very strange if it didn't given the width available, but you'd assume there would be a reason for them to list the maximum at 155mm when so many popular coolers are near to 160mm (though my inner cynic says it might be to sell more expensive cases).
