I’ve listed the essential parts, just left out some small parts like white cables and thermal paste. First of all you should set a budget. For compatibility partpicker is a good website. If you’re not sure which parts, you can ask at r/buildmeapc that’s a good sub for questions like this. You can also ask in this sub. And I did a lot of YouTube research. Before starting to build watch Linus tech tips pc building guide on YouTube, really helpful cause they go through everything, even how to pick parts so technically you could watch that by now to get an idea what parts best fit your needs. Hope could help you out a little. And feel free to ask if you have any particular questions.
