h100i Will it leak?

I'm starting a new build and this time i wanted to some overclock, so i was thinking to myself should i get an h100i. i know whater and computer parts dont mix. so i am worried about it leaking on my 670 4gb. what are the chances it will leak?

I don't do probabilities... I DO have a H80 though, no leaking thus far... Do a google search maybe to see if it's been a problem for anyone else? Remember though, if you're doing water cooling, you're probably OC'ing, which means you're already willing to put your hardware at risk yah? So just do it! I love my H80! 

If you think it's not worth being able to OC and have gorgeous thermals, then don't do it! :-D
