tatmMRKIV, what exactly is your question? :confused: Do you need help to design the cooling system?
The hardware you listed, seems a pretty good choice for OC'ing.
Do your homework on the memory kit (compatibility) as it will affect your overall OC potential - actually if OC is your main goal you should consider less RAM, like 2X4GB, but very high frequency (of course, you can have 4x4GB too, or even higher, but it will cost...).
Personally, i don't like HDDs with too high capacity - if there's a failure, you're loosing a lot. But it's your call...
Now, regarding the cooling part.
Let's start with the end - forget the peltier cooling! As nice is it sounds, as suck can be... The biggest problem with it is that can cool below ambient temp, which means that you will have condensations. You have to be very dedicated to deal with that...
As I see, you're going water cooling way - good choice, I like it! :cool: A main question you have to answer yourself is if you want a closed kit or a custom loop? The closed kit (as the H100 is) is simply to use, but cools only the CPU - and usually their efficiency is more closer to the top air coolers, way below the custom loop's efficiency.
The XSPC Raystorm and the RIVE block pushes toward a custom loop. Getting a waterblock for the RAM is OK, but don't expect too much from it... If you have a limited budget, focus more on the graphic card selection and a block for that! If you're budget is really tight, just forget the custom loop, it can get expensive...
You didn't mention anything about the radiator(s)... Don't forget, those are dissipating the heat. How many of them you want (it depends on how many components you want to cool)? Which is your case, will those rads fit in? Or you want an external cooling?
