really

This build took me three years of begging my parents for funding but finally I managed to convince them to let me buy it as a project to embark on during quarantine. The full parts list will be here. I am a 15 year old student and after building a drone with my science teacher in 7th grade from scratch, my science teacher encouraged me to look into building a PC. Immediately after he told me this, I watched every LTT, Bitwit, Paul's Hardware, and Jays two cents video that they had ever posted but I never managed to get the money to actually build it until recently. The desk is not my choice but apparently its like only four made so I mean like.... Any comments or suggestions are welcome!

No problem, glad I could help.

Personally, there's a few things I see that can be improved upon. Changed a few things around to improve the ptp of the build, slightly cheaper motherboard that can still handle the 3700x very well while still fitting the white theme, and swapped to a more reasonably priced PSU that is still a great unit and plenty for the system, I also added/upgraded a few things. I added a mass storage drive for games and such that don't require an SSD and also upgraded to a better memory kit, case, monitor, headset, and keyboard. And all the changes came to just under your original total. So you get a better computer and peripherals for less.

I really never noticed a difference between 144hz and 165hz. 240hz that's a different story. Like this one if you really want an IPS panel.

VA is the compromise between TN, and IPS. Some are good though make sure brightness is good not to dark above 300 nit at least.
 
Also the headset maybe go for the alphas dual drivers.

It's a relatively new model it looks not too bad, especially because 1440p 165hz often cost 400 or more. VA panels have generally worse colors than IPS but better contrast, while IPS panels suffer from the IPS glow near the edges. It is down to preference there I think. This model probably has good enough colors, especially for gaming I think it's not a big deal. It is also a flat panel and it looks well equipped with ports. Since it is so new I can't find any in depth reviews but from the specs and some random comments about it it looks like a solid pick.

That monitor is pretty pricey for a 1080p 60hz. Not the greatest for gaming either. I think you should do a 1080p/1440p with 144hz for around the same price if you can. The rest looks perfect.
 
Monitor options such as this one even cheaper

what is "budget" for you? by looking at your gpu, Is it around 500?
ASUS TUF Gaming VG27AQ seems interesting in that category, if you're fine dropping to 144hz I would go for the LG 27GL850 instead though.

You likely will need more RAM for music production and video editing. If you want to stretch the budget you could go for 2080 Super.

I'm going to go with @JM21
As a video editor and someone who leaves stuff open in he background 32gb of ram is super nice to have.
I'd also pick up a big 4-8tb X300 as they are some of the best drivers for the money

Ebay has a better selection of used item.
