dang, looks pretty nice! if you'd like to improve/nitpick, heres few pointers:
-c a b l e m a n a g e m e n t
putting your pc on the desk. i saw your other comment on how you're worried about it collapsing. im not sure how stable the desk is, but it seems fine. you could get a few cheap l-brackets for support if it really worries you, though. i also built a pc for a friend and he killed it a month later due to knocking a glass of water on it, and since his pc was on the floor, damage was maximized.
-get a bigger mouse pad! heres one off amazon that had alot of size options. bot having your keyboard wobble about as you're gaming, and not having yoor stuff so close to you os a really nice feeling.
heres one a friend recommended to me: https://www.amazon.com/Extended-Custom-Professional-Gaming-Mouse/dp/B086D9X8TP/ref=mp_s_a_1_23
good luck to your future gaming endeavors!
