He has soooooo many videos, and he is an authority on water cooling.
For the third question I have my own opinions. The rule is one fan slot per block. So if you're running 2x video cards and a cpu get a triple 120mm or 140mm radiator. If you're running a single video card and a cpu get a dual 120mm or 140mm radiator. The only exceptions to the rule are components that generate trivial amounts of heat such as motherboard blocks, memory blocks, and HDD blocks. They can usually piggy-back on your other components. For example, if you're running a cpu block, dual gpu blocks and a motherboard block, you can get away with a triple radiator. More radiators are always better, if your pump(s) can handle it, as you can then run fans at a lower speed.
Always get the thickest radiator your case can handle. I know you said you're going for aesthetics, but what's more pleasing, a quiet computer or a tiny thin rad with 40 db fans on it? This way you can minimize FPI (fins per inch) yet still maintain good heat dissipation. Lower FPI rads need less air flow and thus you can use really really really quiet fans. In my opinion, the whole purpose of watercooling is a silent build that offers superior cooling.
Many people run push/pull fans (one fan on either side) on their radiators. This doesn't help performance significantly and i only recommend this if you want to show off your fans or if you're trying to shave off one or two degrees at a time. There are many expensive things you can do to slightly improve the effectiveness of your loop. Most people recommend fans in a pull configuration, i prefer push as then the side of the radiator with no fans on it isn't exposed. Fins bend easy.
You can 100% mix metals in your loop, copper and aluminum included if and only if you use a corrosion inhibitor. Copper and aluminum mix too well, and you'll get a nasty surprise in your liquid if you mix these two common metals in your loop without corrosion inhibition.
Most radiators are made pretty much the same and many come from the same factory in China. There are only tiny differences between two radiators of the same pass configuration of the same size made by two different companies. Basically many companies just stamp their logo on the radiator. This is akin to how many all in one liquid cooling systems are made by coolit or antec but have different names on them.
Radiators are one component you really have to flush out well before using. Most have slag in them. This is nasty stuff like flux and heavy metal residue. You can flush it out with tap water as long as you then rinse it out with deionized water three times after your put tap water in your radiator. Tap water will ruin components if you live in some cities like Edmonton, so rinse it out well with the DI water.
