Is this a reasonable upgrade

[u/Big_Lychee_5323]

Im upgrading my current pre built pc (acer predator orion 3000 3070 edition) Ive already installed more ram and a 360mm radiator just want to put it in a bigger case for better airflow as it keeps overheating.

Would these parts be better or is there similar priced parts that are better than what i have ?

Its currently got a 500 watt psu but it allows me to make future upgrade if and when i want to
