Is this Ryzen PC compilation good (for fortnite and office)?

These are the parts:

Mainboard: ASRock A320M-DGS, AMD A320 motherboard - Socket AM4

Case: Kolink Sanctuary Micro-ATX Cube - Black Window

Processor: AMD Ryzen 3 2200G 3.5GHz (Raven Ridge) Socket AM4 - boxed

Memory: G.Skill Value Series, DDR4-2400, CL15 - 8GB dual kit, black

SSD: Crucial MX500 2.5 inch SSD, SATA 6G - 500 GB

You want to use a 2nd generation Ryzen. Since you should better use a B4xx board to get everything out of the processor. And the RAM I would take at least 16GB.

If I want to have this processor but which board do I need?

Is only an example. But the board is pretty good.
