Would this CPU liquid cooler fit in my case?

yes, it will fit. the casing that you have is very large enough for that cooler and the cooler is just 120mm. you can install it in the rear but maybe you need to remove first the preinstalled fan there.
 


Yea there's a pre-installed fan here, I might put it on the case side.
 


yeah, or in the front for intake of cool air.
