Can someone help me make a pc for my little brother’s birthday?

Hi, my little brother’s birthday is coming up soon and I was hoping to upgrade his old pc. He had a difficult last few years so I want him to at kleast have some comfort if he needs to. IMPORTANT NOTE: He bought an AMD RYZEN 5 5600 and a MB GBT AMD AM4 B550M DS3H AC. He has yet to install them both. How would you upgrade this? I don’t have that much money, what change would be the most important and has the most impact?

Rate my first PC

CPU: 500Mhz AMD k6-2 10.2 GB HDD 64MB RAM 8MB GPU

WiFi card

Following up my previous post about card vs USB device I've decided to go with a card. Here is a screenshot of my new (to me) PC specs (not sure what case I have but it's BIG) What card would work well with these specs? I'm not too worried that case size will get in the way there's a lot of room yet to upgrade which is half why I got this PC.

When I launch steam, the taskbar displays the generic application icon instead of the steam icon. I have tried deleting the icon cache folder, also DISM and SFC, and reinstalling Steam but nothing is working. Any help is appreciated.
