I have not kept up with computer news. Whenever I go to buy a new computer component I research and mentally spend hundreds (if not thousands) of dollars in my head before I get back to reality and actually buy what I need. So I know little about what is on the market now since the last component I bought was a 512 stick of kingston value ram probably 8 months ago.

I got a vid card for christmas. Unfortunately it is PCIe x16.
PCI (as in the regular expansion slots in your computer)
e (express meaning it is much faster than the regular expansion slots)
x16 (with 16 lanes of really fast goodness).

What this means is that my two year old motherboard (christmas '03) can't support it. I know I need a new motherboard and whatever I get it will have an amd socket. Probably a 939 but I'm not sure. My parents added a $100 credit at the place they got the card because they knew I would have to buy a new board to use the gift. I am looking at one specific board right now but that is all it is, looking.

Here is my problem. Once I get the new motherboard, cpu, and stick in my new gpu, I want to make it all water cooled. Now I have built several computers in the past but I have never overclocked (don't want to risk a dead cpu), I have never case modded, never any DIY computer hardware other than putting all the pieces together.

I don't know where to start with a liquid cooling system.

I know you need water blocks (one for the cpu, and one for each additional point (chipset/gpu/hdd)), you need a pump, a radiator and fans, and I think a water tank for overflow when the water heats and expands, but I'm not sure on that one. I know there are different sizes of hoses and logicly bigger means more water flow.

So where do I start? What brands do I look at? Should I buy an all in one kit, or build it myself out of blocks, hoses, and other components? Should I even bother with a GPU point? The board I am looking at has a review that says the chipset is very close (a little under) the video card and could make any cooling upgrades (to the chipset) difficult, that and the chipset runs hot on this board, should I bother with that board or should I leave the stock fan?

As I said, geekness requested.
