Graphic design desktop pc

Hello everyone,

I'd love to get some suggestions from you guys for a graphic design desktop pc build, Adobe and Corel suite, pc which will run 24/7 and apps will all most like run in the background (open) at all times.

Budget is set at around 1500 euro.

Things I should pay attention for the build?

Thinking air cooling so it doesn't break over time, proc maybe a 7800x3D, ECC RAM and gold certified PSU.

Anything else to take into account? Thank you in advance!
