I'm sure this idea crossed the mind of everyone wanting a above average performance carPC. Yes, a water cooler inside a carPC

At first i thought what a crazy idea but more i thought about it, the more i want to do it.
Does anyone here have enough experience with water cooler to say if it's a bad idea or not?
My carPC is crammed in a tight spot with little airflow so it would be somewhat useful (i just need a reason to put it in there).
The first problem i can think of is, well it's winter and water + cold = ice, so maybe mixing alcohol. Worst comes to worst water cool will be a summer thing.
I just think it would look cool in my future acrylic case and not to forget braging rights
(to those ppl who like to ******, sorry if this has been asked often, i did a search and too many results came out for "water" and "cool" that were'nt what i was looking for)
