Great list! RAM is dirt cheap right now. I got a 32GB kit of G.Skill TridentZ RGB 3200Mhz for $215 a little over a month ago. That same kit is $200 now and the 3000Mhz kit was like $165 last time I looked.Nice build, I pulled the trigger last spring (before the 9xxx series Intel chips launched) and ended up with a pretty similar spec:
Case- Fractal Define C
Fans- 2x Noctua NF-P14s intake, 1x Noctua S12A exhaust
PSU- EVGA SuperNOVA 650 GS
Ram- G.Skill Ripjaws 8GB 3000 MHz C15 x2 (RAM prices at that time were double what they are now, hence staying with 2x8GB)
SSD- Western Digital Black NVMe 500GB + Samsung 840 500GB (from 2013!) + 2x2TB WD Red HDD
GPU- Nvidia RTX 2070 Founders Edition (with Nvidia employee discount from relative)
Cooler - Cooler Master Hyper 212 Plus with Noctua NF-F12 fan
CPU - i7 8700k, stock clocks until heatsink upgrade
Mobo - ASUS ROG Strix Z370-H
A few things like the GPU and NVMe drive are more recent upgrades.
Monitor: Dell SG2716DG 27" 1440p 144Hz G-SYNC
The trigger finger is currently hovering over:
Cooler - Noctua NH-U14S
SSD - Intel 660p 2TB for bulk storage, to move the spinning disks to my secondary PC
RAM - 32GB kit
The most recent parts I've picked up are a Cryorig H5 Ultimate cooler and a CableMod RMx Essentials PSU cable kit.
Still missing the CPU, mobo, case and keyboard.
