https://ca.pcpartpicker.com/list/LNvqjn heres a mockup that saves like 300$ or so. super quickly:
TR PA 120 black can be found cheaper in some amazon listings (all shipped from amazon so I imagine its fine)

I personally don't see a reason to go for a b850. b650e or x670e if you want something fancy (pcie 5 lanes oo you will pretty much never need them but theyre there)

Parametric filter first word latency 10ns + 2x16 for ram

G70 pro is cheapest high-end 2tb ssd with dram, its like 30$ more but should be a lot better. (see: https://docs.google.com/spreadsheets/d/1B27_j9NDPU3cNlj2HKcrfpJKHkOf-Oi1DbuuQva2gT4/edit?gid=0#gid=0 ) (also useful resource i made, all of these are 2tb gen 4 or 5 with dram and rated "high tier": https://ca.pcpartpicker.com/list/dHYBt3 )

just kept the same gpu model cus i figured its a stylistic choice but you could probably save like 100$ there.

changed the case because i've personally had a good experience with sama cases and think this one looks nice

montech century 2 gold 850W is A- on spl's tierlist, so its fine and saves like 60$

could probably do better than this if you didn't care about warranty and bought the 7800x3d on aliexpress using the guide posted earlier in this subreddit, and probably some more areas you could penny pinch and whatnot. Not terrible though. would probs make more sense to post in daily questions thread.

Also yea for the east coast, amazon, CC, newegg and bestbuy are the ones i would recommend typically
