Max newbie looking for help!

Hey everyone,

Hope you guys are doing great!

I am planning to build my first gaming PC. I got a budget of around 1300 euros. I have decided following configuration from partpicker. Can you guys please give me suggestions on case and power supply? Also suggestion to change my chosen components will also be a great help! I am very new to this and your help would be really really helpful😁.
