I've obviously not been clear about what I meant. Let's say you buy this kit with a dual-core, and later, you want to upgrade to a quad-core. When you start overclocking the quad, you feel the temperatures are a bit high. So, you could go out and buy a complete new set of components, get your case cut etc. etc. of you could just swap out the radiator for a PA120.1 or a TFC 120mm and upgrade the block to whatever the equivalent of a nozzled FuZion is at that point.
My point was, that with this kit - you can do that because these are all perfectly decent 'custom' components with standard hole sizes and threadings for the barbs. If you want 1/2", just swap everything over. The cunning bit about this kit is the carrier that mounts the whole lot onto the case with no cutting, drilling or other metalwork skills involved. It's custom without most of the effort. And even if you want to upgrade the pump, it's possible because the original Alphacool bracket will take a DDC with the Alphacool top.
Custom pretty much means you have to drill the case to get a perfect fit. That's what puts most people off water, that and the bickering over what is and isn't a good component. On here, if you don't buy a D-Tek FuZion/Thermochill/Laing combo then you're highly likely to be told that you purchased foolishly. That's a shocking attitude, and we should be encouraging people to get into water-cooling, if only as a means of shifting our existing kit to them as an upgrade in 6-12 months time.
With this kit, Yewen has picked some decent bits that will give the right results for the money, no fussing or messing about and no metalwork. And, as as referenced above, the whole point of my original post was that this kit is upgradeable later, should you need to or want to. You certainly couldn't say that of the Thermaltake Big Water SE.
Hopefully, that's a bit clearer now, my apologies if I was confusing before.
