I would agree - small custom watercooling builds are a bit more difficult for someone's first custom loop build. It isn't impossible, but if you struggle with some of the overall concepts of watercooling and design, it will be harder to do.
That is, unless you follow exactly what someone else did to re-create their build, then its just a matter of following the steps.
