Should be plenty of basic info in the threads here talking about Fluid Dynamics. Water flow properties is the wrong term and might be why you are getting few results.
You should keep post about "Water flow properties" seperate from WCing loop questions because they are separate topics and misleading.
If you plan to WCing with all that stuff planned
1) have a large case because you wont be able to loop that in midtower or fulltower. SERVER tower or larger case is required.
2)with a bigger case I would just air cool the ram and HDDs. Sounds like you wont be having any BH-5/CH-5 UTT overvolting at +3.2V or overclocking HDDs either so it doesn't warrant watercooling.
Good 5 1/2" HDD cooling enclosure is enough.

3) Chipset WCing is not neccessary. These will do the job
