The Gigabyte B450M DS3H motherboard, despite being on a severely low budget, is an excellent match for the Ryzen CPU. 

8GB DDR4 , 2666 MHz Memory Speed, 2666 MHz Clock Speed

We selected a single 8GB DDR4 memory stick as our RAM. We chose a single stick of RAM rather than a 2x4GB kit to use dual channel memory for two reasons:

256 GB, 1600 MB/s and 1000 MB/s in read and write speeds, NVMe PCle Interface

The TeamGroup MP33 256GB SLC can temporarily store your operating system, apps, and some of your games. Its read/write speed is 1600/1000 MB/s, which is not the fastest, but because it costs only $30, it is a great option for this low-cost setup.
