I currently own a system with a i7-4930k and I'm going to wait for the Ryzen 5800x which should be released in less than a month. Right now Micro Center has the power supply I want to buy (Seasonic Focus 850w, which goes out of stock frequently at that store), and I can order the case (Corsair Carbide 275Q) from Newegg.com. I plan to purchase the motherboard (Asus Strix B550-F, hoping it will have the latest BIOS) at the same time I purchase the CPU, RAM, and CPU cooler, which will be sometime next month if the CPU is in stock. Is it a good I idea to buy the case and power supply now while I wait for the 5800x to be released, especially if that power supply I want goes frequently out of stock at Micro Center? I rather purchase as much parts as I can for my upcoming new system from Micro Center rather than buy all the parts I need online.
