I think you missed #6 above... but I like your watercooling page!
The bottom line is that there are many factors in selecting different components. If you know all the factors, and you have a value/answer for most of them, while the rest leave you pondering about what to choose, then we'll be happy to help.
Example: a pump.
In my case, the price was the limit: no more than $50. Then, I really didn't care about flow rate, as long as it was decent. The primary selection factor, after price, was the pressure it can deliver.
So I got a Little Giant 2-MDQ-SC for $40. Max flow~550 gph, and it deadheads at 14.6 feet. It has NPT fittings, which fit nicely any PVC fittings popularly available. No metal here.
Of course I neglected the noise and ventilation that this thing needs, since it draws a max of 180 Watts, but the motor coils are completely isolated from the water, as this pump is a true magnet driven unit.
So now I have to setup a special vent just for it. The pump is also more than 10 inches long, which is not an easy fit.
Is this pump good? You tell me. Btw, it can push 3.5 gpm (aka 210 gph) through a heatercore
