Interesting but also introduces more costs as refrigerant is heavily regulated and if for some reason it leaks can lead to health issues depending on the amount and type of refrigerant.
Tbh perfectly happy with what i use atm cheap water cooler cost £50 had no issues with it, honestly don't see the point to spend the vast amounts on better, obviously it's a hobbyist thing and so you can spend as much as you want for different reasons but for the sake of a few degrees in cooling well at what price.
