First thanks for making a great compilation of good information, esp those new to watercooling (Like myself), but there was one part that worried me when I read it, and that was this:

I feel that even though I am new to this, that this is a very unsafe and bad practice to do. Just 1 week ago there was a thread made by a person Here
that had a tube pop off using a method close to this. 3/8 tubing over 1/2 barbs no clamps/wireties.
Now if you read though the thread you will also see he had two pumps going and that the pumps were configured possibly incorrectly and that could have lead to this happening, but there were several other examples posted in the thread by other users that had the same thing happen to them (Tube popping off the barb) even though they did NOT have any weird pump issues happening and used 7/16 tubing over 1/2 barbs.
I guess at the end of the day FAQ's are usually for new people that are looking for some good, safe and sound advice to follow when getting into watercooling. While tight fitting tubing over barbs might seem safe, I have read at least a few threads with people experiencing the opposite.
This could potentially cost someone thousands of dollars by following this model (Especially people new into WC'ing). So I just suggest you change it, to recommend people to use wireties/clamps with barbs or at least add an "At your own risk" part to the current section because that style of tube/barb paring HAS been known to come off with other people doing it.
Lastly, I know some people have said that over and over that it's safe and it's worked for them. Well good, I'm glad, but when a new person comes along that wants to get involved in watercooling they want to know everything about it, including the information about the possibility that this could happen and not just that it's totally safe.
Once again thanks for a great guide and good read! Keep up the good work!
