Suggestions for gaming pc.

Hey guys! I’m planning to build a PC that I can start using now for games like GTA V, Fortnite, CS:GO, and indie/horror titles. I don’t need to max out AAA games yet, but I want something stable that can handle long sessions without issues. Goal is to get the base system running with integrated graphics and 16GB RAM, then add a dedicated GPU and extra RAM later when I can. I want quality parts, good airflow (no silly RGB), Wi‑Fi built‑in, and future upgradeability (so I don’t have to replace the motherboard/CPU later). Budget for the base setup is around ₹70–80k(I can increase budget if it's value for money, not for hyped parts). Any suggestions on parts or prebuilt systems that fit this, or things I should definitely avoid?
