While there are many pre-built, sealed watercooling kits on the market today, these kits are little better than a top end air cooler. If space is at a premium these sealed units can be a great alternative to the bulky air cooler however, if you are looking for the best cooling performance this side of extreme cooling (LN2, TECs etc) then a custom built watercooling setup is the best choice.

However, watercooling a PC using custom bespoke components can be a daunting task for the uninitiated. What size tubing go with what size fittings, compression or barbs, bay-res or tube, what pump size, what rad size? these are all choices you would have to make which require a fair bit of research to get the right balance. Thankfully, some companies who make these components separately also bundle them together in a kit and because they are sold in kit form, they cost less than buying separately.
