Liquid cooling and my case

If my computer allows for a 120mm fan at the back of the computer, would i be able to stick a domino alc liquid cooler system into my computer? i have an ecute case, but i heard that i would be able to stick a domino alc into it i don't know about it though.

for an ecute? The power supply is very close to the 120mm fan though, like right next to it and isn't the domino alc slightly larger in length compared to an ordinary 120mm fan?

actually no i don't think it will fit on, since it is wider than a 120mm fan, the radiator thing that is attached onto the 120mm fan. I won't be able to put the top panel on. Wait can i actually remove the radiator piece from the fan and attach it someplace else in the case?
