First of all you need to decide whether you want a bay reservoir or a tube res. I would strongly suggest one of the Koolance bay res's as they are absolutely superb. Then you will need to buy a pump, usually either D5 or DDC depending on your res.

Are you wanting to cool you cpu on this loop as well or just the gpu's? This will determine what size radiator to choose. I would say that for cooling just a pair of 6990's, the absolute minimum sized radiator you want would be a double thick 480mm. If you are wanting to cool your cpu aswell, then you would require an additional 240mm rad

On top of res, pumps and rads, you will also need hosing (for this I would recommend a size of 1/2" ID, 3/4" ID), and fittings (barbs or compressions). Also bear in mind that you may need additional angled fittings to make your loop fit, depending on your case.

The best thing is to plan your loop well before you start the build. Consider different configurations and do some research on flow and parallel/serial loops.

Oh and obviously don't forget the coolant. That's most of it from the top of my head.

Edit: Just saw you're only cooling the gpu's.

Another thing to be prepared for is that whatever you plan to budget for this, it will most likely be doubled by the time you actually complete the project.

I would be considering whether it is worth watercooling a 6xxx series card at this stage in it's lifetime, given the cost involved with watercooling. Or whether it would be better to put the money towards a next gen card. But then I don't know what your upgrade plans are, if any.

yes, that is the symbol for pounds. converted says that 700 pounds is $1104.74.

I wouldn't think that it would cost that much though. I was looking at around $400-$550 for a dual 580 with CPU.

you will need:
(2) http://www.frozencpu.com/products/1..._Acetal_EK-FC6990_Acetal.html?tl=g30c309s1389 (289.90)
http://www.frozencpu.com/products/2...38_Conversion_Kit_317_GPH.html?tl=g30c107s153 (89.95)
http://www.frozencpu.com/products/8...rvoir_w_Flow_Meter_-_Plexi.html?tl=g30c97s168 (69.95)
http://www.frozencpu.com/products/1...ies_Radiator_-_Black_23200.html?tl=g30c95s931 (144.99)

For a total so far of $594.79

Then you need to add the tubing and fittings of your choice.

Fans, fan controller, grills, QDC's, adaptor leads, crossfire bridges, coolant etc..... The cost builds up easily and speaking from experience, you always end up spending a fair bit more than the cost of just the main parts.

That radiator that you listed is 3 x 140mm and will most likely not fit the majority of cases without modding. Since 140mm rads have been shown to give no real benefit over 120mm rads, I would suggest a 4 x 120, depending on your case.

Also as I said before, I would recommend going for a res/pump combo. It compacts everything into the drivebays and really tidys up the case.

I wasn't paying attention to the rad. The 120's are fine.

CF brindges he has as he is already running the cards.

Fans as fan controllers are less expensive over at newegg than they are at frozen CPU.

I meant watercooling CF bridge for the waterblocks (look at the EK bridge if he is using EK blocks), not the electrical ribbon thing.

As for fans, you're really best off with Gentle Typhoon AP-15's for watercooling which aren't cheap.

I wasn't saying to use cheap fans. Newegg is overall, even for higher end, cheaper than frozencpu is.

http://www.newegg.com/Product/Product.aspx?Item=N82E16835185060 looks good. High CFM, and the AP-15 isn't listed :(.

http://www.frozencpu.com/products/1...Fan_-_1850_RPM_D1225C12B5AP-15_Hot_Item_.html is what their search shows for the AP-15.

Aside from the fact that they are rather loud, the Slip stream fans are designed to be used in free air, they are not good radiator fans due to their relatively low static pressure.

When it comes to moving air across a radiator, nothing really beats the AP-15's. They are also incredibly quiet.

well, as I said, newegg doesn't list anything for the Ap-15. frozen CPU listed that when I searched exactly what you typed for the AP-15.

Shop around, frozencpu is pretty overpriced. Look at jab-tech, or sidewinder computers, they don't have quite as much selection, but the shipping is cheaper and most of their items are too.

Well someone from the U.S will have to guide you based on budget as I only know of UK based shops. But these items from Koolance would be a good start.....

I think you're going to struggle to get anything bigger than a 360mm radiator into that case, which is certainly not ideal.

I need a bigger case? What could possibly be larger than a haf x? And are those the only 3 parts i need?
