I'm really interested in water cooling, but what are the actual major advantages of it? At first I thought that it would be nice because you would have a much quieter PC, but when you think about it... it won't be that much quieter because you'll be adding more fans for the radiator.

Anyway though. I'm only looking into cooling my CPU for now, nothing else and am curious on the type of radiator to get. Would a single, double, or triple be good just to cool the CPU?

Since this is my first time thinking about water cooling, I don't know much about the 'good' and 'bad' brands. So if you can recommend me some nice parts like the CPU block, radiator, and pump I would really appreciate. Also, could anyone let me know exactly what parts I would need?

Sure.
You need
1.cpu block + 2 barbs
2. Radiator + 2 barbs
3. Pump (some have built on barbs)
4. resevoir + 2 barbs to fill with fluid and have air come out of the line (bleeding)
5. tubing (1/2" ID 5/8 or 3/4" Outer Diameter.
6. Clamps or zip ties to make the tubing snug on the bars.
7. Distilled water or some type fluid for the system.
8. fans for your radiator.. (I recommend yate loons)
9. The screws for the fans to install into radiator.
10. Maybe coils to go around some of the tubing, where the bends may kink the tubing.

That is basically what you want. (You will also need distilled water from a local supermarket or something)

What about the radiators with the reservoir already in them, are those any good? I'm wondering if it's possible to get all the water cooling parts for like $150ish. They don't have to be brand new, and I'm actually thinking about buying them off here.
