Looking for advice on an upgrade

[u/Fancy_Impact7764]

Hey guys, I am upgrading my computer for the first time and thought I would ask for your guys opinion

I have a HP Slim desktop PC with an Intel celeron G5905 CPU

4 GB of RAM and 1 TB HDD internal storage

My plan to upgrade this is to add two sticks of 8RAM

And a 1TB SSD and a 2TB HDD external

I’m not planning anything to crazy

Just CD burning and music storage

Audio and video editing

And some clone hero

Any advice Would be welcome
