Help radiator/case problems

So i have a diy pc shadow case, Asrock z170 extream 6 mother board, i5 6600k, xfx r9 380x GPU. This is my first build as well as my first liquid cool. I was going to do an custom loop, but my wife bought me a Swiftech h220 x2 prestige edition. I went to put it in tonight and it does not fit on the top of my cas. Any suggestions? I am not against buying a new case. I just don't want to buy one and the radiator pump res combo not fit again. Any help is appreciate d.

Is the radiator physically too big?

if you want a custom loop the h220 x2 prestige is not it

You could sell the kit and pursue a custom loop or abandon that idea and use it.

Either way the case you have is problematic. However cases are subjective to what you like.

Do the research and choose one that will work for your needs

Phantek and Corsair are both good companies to start looking at
