Pretty much there are two options for watercooling.1. Custom
2. AIO (All-In-One)
What's the difference? Custom, well it's just that. Custom loops involve making your own loops and configurations depending on your needs. I.E. you can bend acrylic tubing if you want a clean look. You could use regular flexible tubing because you're not experienced enough to bend tubing or are on a tighter budget. AIO on the other hand gets rid of choosing pumps, tubings, fittings, reservoirs, gpu block, cpu block, and fans. Everything comes in a package already in a supposedly leak proof closed system meaning you can't take it apart.But what are the advantages of custom or AIO?
Custom if any parts break or if you want to upgrade or change looks you can at any time by taking whatever you don't want on it anymore off and replace it with something else. AIO on the other hand removes the required maintenance and the need to having to take apart your setup for cleaning. I.E. if you don't use plasticizer free tubing your loop will get dirty in a custom loop. You don't need to maintain anything for AIO setups.What are the disadvantages of custom or AIO?
Custom can cost a lot more, can be complex, and requires more time and careful planning to make the design and installation a success. AIO is harder to fix if the pump goes out or the tubing springs a leak due to either poor manufacture design or workmanship.So which one should I choose?
Pretty much the one that fits your needs. If you just want something that works and performs well without having to do much then AIO is the way to go. But if you want fancy lights, reservoirs, colored tubings, colored liquids, and heavier customization then custom loops are a much better option.

But becareful as some sites have closed i.e. FrozenCPU, don't try to purchase anything from there. And Jab-tech is basically gone and so is Petras.
