Pre-built Desktop for TD use

Hi all,
I am thinking about purchasing the Lenovo Legion T5 26AMR5 (ryzen 7 3700x + rtx 3070). Does anyone here have experience with the quality of the lenovo pre-builds especially regarding bottle necks/ airflow/ general quality of the Build?

(Lenovo Legion T5 26AMR5 | Paradigit)

My main concerns are

  1. if the nutrition of 550 W enough for the r7 3700X/RTX 3070?
  2. If the CPU fan is good enough (The specification says 150W and large blades)
  3. If the airflow inside the tower good enough

Thanks :slight_smile:
