need help

Hi, this is my first PC build and I'd like to know any suggestions you guys might have. I'm planning on buying this pc when nvidia releases the rtx 3000 series and have some questions: 1. Is it possible to control all rgb lights simultaneously with one software? 2. Is this board compatible...

So someone is wanting to buy me my first gaming pc but the only thing is it has to from either bestbuy or amazon and the budget is $800 if it went over $200 I could cove it if there was that much of a difference in hardware and spec. I do want to be able to upgrade this pc later down the road...
