I don't agree with saying that it's easy to have watercooling. It's not.
It's easy to get a compatible components list and assembling it, that's true, it's not more difficult than when you first learned how to work on PC's.
However, loops have a LOT of small and terribly explained details that can make your system inefficient or prone to failure.
Maintenance can be a severe pain if your loop is not designed properly. If something goes wrong and you have to clean your loop, it's a whole day of work at best. And when you ask for help on how to clean it, the thread will turn into an argument on who has the best "grandma's recipe" for cleaning loops.
I've seen so many "experienced watercoolers" act cool and fancy but putting themselves in...
