Can you post the configuration link?
The 5700G has integrated graphics, which you probably won't need if you're getting a separate GPU like the 3060, so may be better off with a 5600x or 5700x. A better cooler may be an idea - the 5600x runs quite cool (I think the 5700x does as well but not sure), so a Hyper 212 air cooler would do the job.
A bigger (500GB) and faster m.2 SSD for the OS would be recommended, but would bring the cost up. These drives don't run as well as they get fuller, so a 500GB drive would give you breathing room.
A better PSU would be recommended as well (Corsair RMx range, min 750w - the CV series isn't ideal for a gaming PC).
With a Ryzen you will want to look at faster RAM - look for 3200MHz or better (doesn't usually cost a huge amount more).
The 802.11N wireless network card is obsolete - the much more up to date Intel AX200 doesn't cost much more and will be much better.
What sort of monitor (resolution / refresh rate) will they be using?
I would want to rebuild this from the ground up to be honest, there’s quite a few areas I would change.
Please can you tell us your budget, use case, and the monitor that you’re pairing with this, and we can try and spec out something a bit more suitable for you.
