PC parts compatibility

[tenzing.burger]

I am picking parts for my first pc and was wondering if these are compatible.
AMD - Ryzen 5 2600 3.4GHz 6-Core Processor
MSI - B450-A PRO ATX AM4 Motherboard
G.SKILL Aegis 16GB (2 x 8GB) DDR4 3000
Western Digital - Green 240GB 2.5" Solid State Drive
Hitachi - Ultrastar 7K3000 2TB 3.5" 7200RPM Internal Hard Drive
MSI - GeForce GTX 1060 6GB
NZXT - H500 (Black) ATX Mid Tower Case
Corsair - TXM Gold 550W 80+ Gold Certified Semi-Modular ATX Power Supply

I have checked on part picker but I would like confirmation.
Thanks!

Why not use a WD Black M.2 instate of the WD Green? double the price but over 4 times the performance.

I am on a budget so lower price is better
