I wanted a project for this summer, so i decided to build a computer desk that houses the computer in the desk. This will require water cooling. Seeing as i have never done anything with water cooling before i decided to turn to you all for help.

System specs are, i5-2500k and amd 6970 non reference card design. I am looking to add a second 6970 in the future(next summer). I would like to be able to do some heavy OC'ing as well.

I was thinking of purchasing these for now:

XSPC Rasa 750 RS360:

EK Radeon HD 6970 V2 VGA Liquid Cooling Block:

This is an incredibly attractive option for $270. My concern is that the supplied pump will not have the oomph for both blocks and the triple rad. Is this a legitimate concern? I also would like to have a system in place where i can just drop in the second 6970 and another rad(if necessary) without needing a new pump either.

Anyone have any suggestions to have a system set up for <$400 that will be able to support a second triple rad and second card as well?

XSPC Raystorm EX360 Universal CPU Water Cooling Kit w/ D5 Variant Pump Included and Free Kill Coil!

More than capable. D5 = MCP655

EX360 should be able to handle this with a potential dissipation of 500+ watts.. 6970 TDP is ~250w (stock), overclocked i5 is around 135w.
I don't think that rad is really good enough for a 2500k and a 6970, both OCed. I'm not sure about the pump.

But basically, since you're doing this custom, I'd highly recommend getting independant pieces so you can do the best possible install. Especially with radiators, if you just bought a double 200mm rad, triple 180, or hell, just get this 9x 120 you wouldn't really need to add much to it later (if anything)

Price for performance, bigger rads are way better. Bigger fans are also quieter, hence suggesting 180 or 200mm rads.

I'd suggest either an MCP35x or MCP655 pump, although I'm no expert on that.

And with a big rad, you don't really need a resevoir except as an easy fill station, although I've seen pump-top resevoirs can increase performance (easier flow).

Can you explain how you know the rad will support 500W of dissipation? Not questioning the fact that it will, just interested in numbers and such. Also you are confirming that the pump will be able to run another rad and gpu in the future?

Most 360 rads have the ability to dissipate 500+ watts with 1500-1800rpm fans at 1.5gpm for a 10C loop delta. Skinneelabs.com has a lot of these charts and reviews that outline how to calculate this. There is also information in the WC sticky around calculating delta.
