Hello guys! So, I am not new to pc building, just new to AMD. I want to build a complete system, which I should specify will have no case as it will be mounted somewhere under my table, that could run ESports games and maybe games like Gta V. I would pick the parts myself, but, I heard that AMD has some great deals going on with their Ryzen CPU's and all. So I decided that I want an AMD build. My budget is basically 300$ (US dollars, but I don't live in the US) Keep in mind that I will get second-hand parts only, maybe the storage and the PSU will be new, but other than that, I want everything to be second-hand. If any of you guys have any tips leave them down below, it would be highly appreciated! <3
