After some evaluating I eventually chose the Fractal Design 3k, because of the simple fact that it is easier for me to get my hands on and I didn't see that many differences with the corsair carbide 300r.
So I will be building it today and upload a picture when im done! Thanx for all the help ob this build!
An other problem i had was to connect my gpu to my psu, I used the 6pin cables that lead directly into the psu but they didn't seem to fiy completely. I attached pictures of the pins and their fit
