I just completed the following build/battlestation a few weeks ago:
CPU: I7-8700K
GPU: MSI RTX 2080ti Gaming X Trio
CPU cooler: Noctua D15s
Case: Fractal Design Define R6
Boot drive: 970 Evo ssd m.2 500gb
Game drive: 860 Evo ssd 1tb
Media drive: WD Red hdd 6tb (2x)
DIMM: G.Skill Ripsaw V DDR4 16gb 3200mhz 14 cas
PSU: EVGA SuperNOVA Platinum 750w
Mouse: Logitech G900
Monitor: AW3418DW 3440x1440p
Monitor arm: AmazonBasics monitor arm
Speakers: Edifier r1280db
Desk: Karlby oak countertop 74" + couple of Klimpen drawer/table top with legs
Total cost was around $5,000.00. Buying components throughout the 3-4 weeks before Black Friday shaved off ~$400. Everything was purchased from online vendors that didn't charge sales tax except the mouse from a local Best Buy, the speakers, monitor arm, and the desk stuff. Total build time was around 4 hours. Hardest part was installing the Noctua cooler as the springs on the screw kept causing one side to pop out when I screwed in the other, and I had to re-apply the thermal paste because I was concerned it was drying up. One of the screws on the case got stripped and I couldn't remove the side panel so I was afraid I couldn't fit the 2080ti, which is a monster. It worked out okay. 14 CAS latency probably not necessary on an Intel build but I got it for a good price. I was extremely lucky in obtaining the 2080ti, as I wanted this particular card from this maker and it had been unavailable from most vendors since launch date for 2 months; I just happened to check Newegg one night and saw that the "add to cart" button was not grayed out and the site did not say it was OUT OF STOCK in bright red font.
