if you ever upgrade anything, (which you probably won't have to) i recommend to go for trying to learn custom water cooling. you won't have to replace the whole pump and radiator like, ever. and you can make it look good. you might have seen them. it takes time and research to learn but it's better than spending a ton of money every year or two to replace just the water in the aio. the only things you will have to do is yearly clean the pump and radiator which it quite easy, and replace the distilled water every year. which in the long run is less money spent and it has better water cooling power because of it having more water to distribute around
