ADDITIONAL COMMENTS: Ok, so, this is my first build, I'm trying to build a gaming pc with kind of a small budget and I'm looking for advice on the parts and also if there are better options to take for about the same price or lower. There might already be some parts in which I tried to save some money. Also there might be some errors since I'm just a starter in computer building in general.
Here are the parts with the prices of the website I'm bying them from.
Thanks for the fast reply, I'll see what I can do with your suggestions.
Edit: So I replaced the CPU, Mobo and HSF and the price stayed almost exactly the same, so thank you for the suggestions.
Then I looked at the PSU's but couldn't find anything better performance- or pricewise so I stayed with the PSU I had in my list.
Last but not least I looked at the cases and found the Three Hundred Ultimate Gamer Case, it's a great case from what I read from the reviews, and it's a bit cheaper aswell! So I took it. Coolermaster 690 would have been great, but it was really expensive (80 €) so I had to line it out.
