I have a shitload of storage since I don't throw out my old hard drives as I go along; the fastest thing that I have that I run the system and games from is an ADATA XPG SX8200 Pro.
Built last year with a be quiet! Dark Base Pro 900 rev 2 case - great case except for the instructions being the most cryptic bullshit. Have some extra Noctua fans in there as well, although I don't get great temperatures. I have been wondering how much of that is having to forego an intake fan because I have a 5.25" drive in there. A few degrees difference would be pretty significant.
Obviously it cost a lot (not as much as the guy above me - eek), and I still cringe when I see the 2080Ti becasue I know how much it cost. But my only regret is not spending the extra $150 or whatever for the 9900k - sure, the 9700k is great for games right now, but I'm extremely apprehensive that the lack of multithreading will bite me. It already had problems with Red Dead Redemption 2 (although fixable - Rockstar didn't optimise it properly for different setups).
I suppose not getting the Z390 Master might've been a mistake, depending on how good the better-quality sound they have on that build is (has capacity for more hard drives too but I really should start replacing my aged HDDs slowly).
Oh, and the RAM is quite old, but to my understanding RAM doesn't give much of a return in gaming above a certain capacity and speed. I'll probably upgrade it sometime in the next year.
Have a Ducky TKL keyboard and a G502, as well - G502s are way too heavy and I'll try out some lightweight ergos when I have some time.
