Below are some photographs during assembly of the Asrock A300M with an AMD Ryzen 5 Pro 3400G processor.

The Asrock web-site detailing the specs of the A300M: DeskMini A300 Series.

Three noticable reviews on the A300M:

  1. Anandtech has a very readable review of the A300M: Home> Systems The ASRock DeskMini A300 Review: An Affordable DIY AMD Ryzen mini-PC
  2. A short review from Techspot: Asrock DeskMini A300 Review.
  3. A German review with many photos during assembly: ASRock DeskMini A300 mit AMD Ryzen 5 2400G im Test.

1. CPU. Three photos from the AMD 3400G CPU:

2. Power. The power supply of the A300M will provide at most 19V x 6.32A = 120W.

3. Dimensions. The case has volume of at most two liters, exemplified by the two milk cartons.

4. Mounting. CPU mounted on motherboard.

5. Temperature. I installed a Noctua NH-L9a-AM4 cooler. Running the AMD at full speed with full load shows the following temperature using command sensors:

Added, 22-Aug-2020: I noticed that the A300M motherboard has a very significant clock lag. So you are requried to run ntpdate or timesyncd.
