Good evening! I'm thinking to buy a desktop PC but some parts that I want are ''pre-order only'' and I'm not sure exactly how much waiting time ''pre-order'' means. Are we talking about a few days, a couple of weeks or it can be months to get the parts after the order is made? The parts that I'm talking about are :GeForce RTX 3090 GPU and AMD Ryzen 9 5950x CPU.
