One great resource I'd recommend for learning about PC hardware is PCPartPicker. It's not just a place to find parts for building a PC, but it also has tons of guides, forums, and reviews where people break down how different components work together. What I found most helpful about it is how hands-on it is. You can actually see what parts are compatible with each other, which helped me a lot when I was first learning about hardware. The community is also really active, so if you ever run into confusion, there's always someone there to explain things in simple terms. It's a great starting point for anyone wanting to dive deeper into PC hardware!
