And the "best" price for the graphics card in this build just jumped up to $787 from $429 because that price they didn't have any stock, so now just the components alone run almost $2200 before the extra customizations.
Now granted, you don't NEED to have the exact powerhouse components in this build. You could still get a unique looking build that is perfectly capable of handling todays games, etc. at a much lower price point.
I'd say a GTX 1050ti 4GB would be a decent card for 1080p gaming. It "should" retail for $150 but it's been well north of $200 these days. A GTX 1060 3GB or 6GB would be even better, although those prices are jacked up also.
The i5 8600K isn't needed if you aren't overclocking, you could spend $100 less on an i5-8400 processor or you could even get an i3 (the new versions are quad cores now)
With RAM you could drop it in half to 8GB which is really the spot I'd recommend given current RAM prices which have doubled due to shortages.
You could get a traditional IDE hard drive with twice as much space for half the cost of an SSD and it would still perform fine
So there's plenty of ways to cut the costs down while maintaining a powerful system with some cool aesthetics.
Whenever RAM and Graphics Card prices normalize this industry will be a lot better
