Minecraft is not really a high demand game. Nor any others you mention are cutting edge. So no need for crazy stuff.
Case: very personal, but I would go for something nice from Corsair, CoolerMaster or Fractal. Make sure it has good airflow, cable management, accessible dust filters and room for whatever you need. Note position of controls and ports and where you plan to put it.
Power supply: something in 650W range shoult be more than enough. I am partial to Corsair and Seasonic, though Coolermaster are also not bad. Get a well-reviewed model, don't skimp here - good stable power if often key to rest of PC stability.
Biggest decision: CPU. AMD vs Intel. I been using Intel i7s for a long time, so not really sure what AMD has to offer these days. They used to be way behind. Once decided on CPU, make sure you choose a compatible mobo. Asus, Gigabyte, EVGA are all nice. No need to go crazy here, high priced models with multiple high speed PCI express slots are for SLI rigs, you don't need that. For CPU cooling, I toss the stock cooler and go with something like CoolerMaster Hyper 212. It is quieter and cools better.
Memory: again go for a well-reviewed brand. Avoid cheap outliers. Make sure you get the type and speed that the mobo supports. I would go with minimum 16GB. Modules should always be bought in pairs - they are usually sold that way too. It is better to put in two 8GB modules than one 16GB.
GPU - also - Nvidia vs AMD. I prefer nVidia, though likely if you go with AMD CPU, they may talk better to AMD cards. Not sure what AMD has to offer. On nVidia side, 2080 is way overkill. I would say either RTX 2060 or 2070 if you want extra oomph. Go into some benchmark sites, see how they compare.
For storage, I would go with a 1TB SSD. Many mobos today have an M2 SSD slot, so you can plug in there an not worry about SATA and power cables. Your call if you want to include an optical (DVD) drive.
Do not forget to budget about $130 for the operating system.
