The prices of M.2 drives has been up and down over the past 6 months. Right now, they are up. I recommend you hold off on the Gen 5 M.2 drives, or at least just get one for the system drive and a Gen 4 M.2 drive for the data or games drive. The G. Skill 6000 MHz DDR 5 Z5 Neo RGB RAM is excellent, but there are others to choose from.
As Albert Einstein said, "I could have done so much more with a Big Al's Computer!".
