I'm building a PC and I've only done this once before about 7 or 8 years ago.
I have a case (NZXT H510i) and I'm trying to decide whether to jump on this popular RAM deal or not, given that I am probably going to wait a few weeks anyway to see what happens with the Ryzen 9 CPUs. Is the price of this RAM likely to fall much further? Is there new/better RAM coming out soon?
But more generally speaking, is it better to buy all the parts in one go, or in what order would you purchase them?
It's a large sized Lego kit, you need all the parts at the end so it doesn't matter which ones you grab first. Get whatever deals you can find while waiting for desired CPU.
