Help upgrading pc

I have a “skytech archangel 4”

AMD Ryzen 5 5600x

Motherboard- MSI B550 Pro-VDH WiFi

GPU-Nvidia GeForce RTX 3050

I think I only have 16gb ram DDR4

I’m all new to the pc world hints why I bought a prebuilt but I’m ready to try and pull more frames and not blow up my pc doing so lol! I think my gpu is usually what maxes out when I play games such as arc raiders, rust, etc…
