Skytech Prism II Gaming PC Ryzen 7 5800X RTX 3090 for mining/ gaming?

I’m looking at getting a gaming computer and running it as a mining rig. I have $4000-$5000 to put into it. It would mostly be used for mining, but I want to game on it some on my off days. I’ve been looking at the sky tech prism II (link below for more specs) and was looking for some input on how this would do? I want something that I can add additional GPUs too in the future. Any idea on how much I could bring in, in a day with this set up as is? My goal is to try to get to $20 a day. Any advice, or other products to look into would be greatly appreciated!
