Eh, how does it suck compared to air cooling? I mean, yeah it’s expensive and requires more maintenance, but it’s way quieter and keeps the components cooler than air cooling.
E: a lot of people who are saying all the stuff that could go wrong sound like they’ve never built a WC system and refuse to acknowledge that many of these issues are likely operator/installer error. Installation absolutely does require more care and effort than an air cooled system. I’m not trying to suggest anyone WC or that it’s better than air, you do you, I don’t care, but WC is trouble free if done correctly with good components.
