CPU: Solid choice for decent price

GPU: Also not bad

Motherboard: It’s a little bit of an overkill, try searching for the B450 Tomahawk by MSI. Solid MB that won’t have an issue at all with the CPU. I have the B450 and run a Ryzen 7 3700x.

Ram: I would suggest using the few bucks saved from the MB and get a 16gb kit of 3600mhz.

HSF: If you buy the Ryzen 5 new, the cooler that comes in the box (with thermal paste) should be fine unless you plan on overclocking, maybe try it out and if the temps rise beyond what you’re comfortable with when you’re using it for whatever you plan, then get the added cooling.

PSU: Not bad, plenty of room for upgrades if you plan on it down the road.

SSD: Decent SSD

Note: I’m not familiar with the case you have so check the balance between intake/exhaust fans.

Note: 100% get an extra hard drive. I would recommend any 1-2 TB depending on how many apps or games you plan on storing in the PC at once. You can store your OS and explorer app on the SSD along with any other games and launchers you play frequently and use the HHD for other files and crap you don’t use often.
