I’ve been building Mini-PC systems since 2008. I recently got parts to build an AMD Ryzen system based on an ASRock Desk Mini A300.
Those are the parts but in summary:
- ASRock DeskMini A300 Chassis
- AMD Ryzen 3 3200G 4-Core Processor
- Samsung 970 EVO 500GB NVMe SSD
- 16GB RAM
The chassis comes with WiFi. And it now runs Linux Mint 19.3. It supports the 4K monitor with no issues unlike the previous Gigabyte Brix system, which only supported the 4K monitor under Windows 10 and not Linux Mint.
