External power supply unit is included. CPU cooler is not. An AMD Wraith Stealth fits if you take off the bezel. Otherwise, I can recommend the Noctua NH-L9a-AM4.

In the meantime Digitec delivers with Bios 1.7 (was on my new bought on 30.12.2021 and Ryzen 5700G has accepted the Bios at the first go)

Unfortunately, this is very difficult, as AMD has a supply bottleneck...

It is very likely that the HDMI port of the DeskMeet X300 is only HDMI 2.0, not 2.1. This is because no AM4 APU supports HDMI 2.1 - neither the Ryzen 5 4650G Pro nor the 5600G or other APU models on this platform. The HDMI controller is integrated directly into the APU. The mainboard (DeskMeet X300) does not extend the HDMI functionality, but only passes it through. Tools such as CRU (Custom Resolution Utility) also show that the active output is recognised as HDMI 2.0.

No, I didn't dare. The space for the cooler is rather cramped and WaKü plus dedicated GPU is not really an option with this case. The power supply is also rather weak (although I think it should be possible to replace it with a better one) For info, I have an RX6600 with Ryzen 5500 running in it.

You can report/adjust incorrect data by scrolling to the bottom of the specifications and clicking on the "Edit specifications" button or by pressing the key combination Ctrl+Shift+E. The team responsible will then check the adjusted data.

ASRock released Bios V 1.70 on 2021/7/5. New sold Units should be with that.

Must be ordered separately. Preferably something with an Intel chipset.

I have not defined a Raid myself. But have a look at https://download.asrock.com/Manual/RAID/X300M-STX/English.pdf at 1.3

Already figured it out thanks:)

Thank you for your advice. According to our information, a 500W 80 Plus Bronze power supply unit should be included here.

No, there is no operating system preinstalled. I use Siduction, a Debian rolling release, on the Deskmini. It runs great on it.

There is only one type of DDR4 SO-DIMM; no matter what some people add in the description. Observe the frequency; read the instructions. Check out the supported bars on ASRock's homepage on the Internet.
