Is this build actually good?

Yo, building my first proper desktop and wanna go all white 🤍
Before this I was using a Lenovo LOQ with i5 13th gen + RTX 4050 6GB + 24GB RAM + 1TB SSD, so this is gonna be a pretty big upgrade for me 💀
New build + prices I found:
Ryzen 5 5600 — ₹12,499 (avikaretails)
Sapphire PURE RX 9060 XT OC 16GB — ₹57,999 (computechstore.in)
MSI PRO B550M-P — ₹8,300 (mdcomputers.in)
T-Force Delta RGB 16GB (8×2) DDR4 3200 CL16 White — ₹13,500 (pcstudio.in)
DeepCool PL750D 750W — ₹5,399 (avikaretails)
NZXT H6 Flow White — ₹10,500 (pcstudio.in)
1TB SSD — already have one
Comes to around ₹1.08L.
I’m planning to buy everything from different stores depending on who’s selling each part cheapest, then assemble it myself.
Is this setup actually good or am I doing something dumb 😭
Also, is buying from different stores fine as long as they’re legit/reputable and the parts have proper warranty?
Anything you’d change? Mainly wanna keep the white aesthetic but get the best performance possible.
First desktop build btw, so any advice is appreciated 🙏
