Before people start asking I bought that RTX 2070 when the GTX 1080 was starting to get more expensive. (and I liked the gaming Z design)

(edit): now that I understand alot more about PC's since my first build I can safely assume that my first build didn't have alot of beginner mistakes at all. The only things I would change now was 1: maybe getting a cheaper motherboard, because I was thinking too much ''more expensive is better''. 2: seeing as the total cost of this build is over 2k, I could have gotten better RGB fans, because the anidees are basically 10$ per fan. 3: I cheaped out on the power supply a tiny bit and people probably don't recognize product line at all, but luckily it never gave me any problems and it was the best rated power supply on amazon.de. next time have to save more of my budget for the PSU. (optional) 4: RTX 2070 could've handled 1440p screen fine, so maybe I shouldve gotten a 27 inch 144hz 1440p dispay instead of a 27 inch 240hz 1080p display.
5 (even though I can change this easily): 500 Gb SSD is pretty good but I know I will have to buy either a new 1T or 500GB SSD.
Let me know in the comments what you would change to make a better 2k build!
