AngryWarlock :
Yea this is gaming build which I would like to make youtube gameplay video's and animations too. I chose for i7 because of the hyper-threading, I'm already doing some animating, and I want to make youtube video's so I'll stick with that. Also, I have no experience with overclocking what so ever so is that hard? Because I would rather not risk failing someting with that kind of price tag, you know?
The case is just a personal choice, I really like the design, the multiple color LED's and it has a great airflow so yea. But thanks a lot for the tips, if you could help me out with these questions too, that would be amazing
The I7 is worth it if you are doing content creation.
Even without overclocking, the GTX970 is still a better option, but yes, overclocking is simple these days with very little risk if you are just careful and do not take it too far.
Case is pure preference as you say.
Remember to change the PSU.
EDIT : The voltage on the RAM does not matter THAT much, but if you get 1.5v RAM then its "officially" supported by the CPU, but yeah, not important to be honest.
Avoid that PSU, also overpriced.
Here is a tiered PSU list, only get units from Tier1, tier2a and tier 2b.

And yes, recording with this system would work great.
