Well I have no idea what an AMS3C is, but yer basic water cooling setup requires several pieces:
-A decent water pump
-reservoir for pump, i.e bucket (unless it is an inline model)
-a waterblock
- a way to remove heat from the water
-lots of hoses and hose clamps.
That is the basic system right there. There are 1 Zillion ways to remove the heat from the water, most common is a small radiator- usually a car oil cooler. But you can get very creative on this point.
Not very complex is it? I advise you read everything in the "Water Cooling" section on the front page. That will give you the general idea.
Like most people here, I also advise you build your own rig- everything but the waterblock can be assembled with nearly zero effort, and even that isn't too hard if you are patient.
If you aren't patient you can buy a kit with the whole setup in 1 box, but they cost quite a bit more than if you build it yourself. Like $100 or more for kit; my homemade cost me $25 total. I've never bought a kit.
Peltiers are scary little toys that can ruin your day fast unless you REALLY read up on them. At least they were for me!! Get the basic H20 system down first then think about peltiers.
As for brands, the Danger Den and be-cooling water blocks worked well for me. Your mileage may vary. The rest of my stuff came from the All-for-a-Dollar store.
Hey that was a big post, hope I put something useful to you in there : )
