Antec h20 k240 cooler in Phanteks P300 case?

[falkirk107]

Monring guys,

I need help. I want to purchase watercooling: Antec KUHLER-K240 Kühler H20 K Series K240 240mm All-in-One Liquid Cooler - Wootware

I want to know if it will fit inside my case?
Phanteks PH-EC300PTG_BK Eclipse P300 Tempered Glass Black Steel ATX Mid Tower Desktop Chassis - Wootware

I am just concerned as I see the case has got space for 240mm radiator and the specs are 277mm on the Antec.

Thanks guys!
