I wasn't sure how much over 1200 you expected to spend, so I tried to cut it as close as possible to the cost of the parts list you listed earlier yet retain the same performance. You may want to pay extra for a power supply with modular cabling.
My French isn't very good, I last studied it in high school years ago, does material.net have a policy on matching the prices of other retailers? Some retailers offer that and you may be able to cut costs.
Here's a more balanced build.

I swapped the overkill NZXT Kraken X61 for the 212 Evo air cooler. That air cooler is already good enough to overclock to 4.5GHz or so, I highly doubt you need to spend that much on a high end water cooler that you probably won't be using to the fullest advantage with the i5 4690K.
The Samsung 840 Evo is no longer recommended due to it being discontinued and replaced by the 850 Evo as well as having performance issues. I recommend the Crucial BX100, it's an excellent cost-effective SSD.
The Gigabyte GTX 970 Windforce is a black graphics card that will better complement your black and white color scheme than the red and black MSI GTX 970. A white and black version of the MSI GTX 970 exists I think, but I am unsure of how much it costs and which retailer sells it. It should also be called the Krait edition?
One last thing, the case you chose didn't have a price attached so your parts list total should be even higher. I don't know if that means you're buying it from an unlisted retailer or not. I substituted the decent NZXT S340 instead.
All in all, I was able to save a bit over $130 even factoring in the cost of the S340 case, without compromising performance.
