You can do this for 2500 and have headroom to wipe your tears of joy with money leftover:

5900x 3080 X570 tomahawk 850x Corsair PSU fully mod Wd black sv750 m.2 nvme Your ram of choice

NH-d15 (although - if I have the choice to keep water near my computer or keep water away from my computer parts I choose the water away...? So this is a fan there’s no water inside. Longer life and less failure points by about 20x)

Lian li o11 cause that’s the case you want. If I could switch your water cooling to a fan (cheaper) I’d say get an airflow case. Looks great and (cheaper also)

Then get a 1440p 144 gsync and avoid terrible stands to vote with your money that those designs should be faded so hard. Or get a versa mount.

Ikbc keyboard cherry brown switches - buy a 10 cent bag of key dampeners if you work in an office or at home with someone who doesn’t want to hear clacky clacky. Also more silent switches than that. Hell, visit, and get lost in the mechanical keyboards subreddit. You think this is a custom build? They do it all over again from the frame up with keyboards. Inspiring. Anyway buy the ikbc it’s on Amazon for cheap and that’s a great option ive found.

Logitech 305 with the colors. Get the lilac. Everyone will be jealous.

If you have more money to kick around buy strimmers for 8 pin and 24 pin. No rgb fans. Strimmers look classy and there’s enough unicorn vomit for one man or woman, but not so much that you’re slipping in the stuff....

Good luck! Here for questions.
