Has anyone managed to get Proxmox running on the MINIS FORUM UN305C ?
With me the installation throws black screen even before the GUI was called.

Can you try the following?
In the bootloader, select "Advanced Options" instead and then "Install Proxmox VE (Console Mode - nomodeset)".

This avoids loading any graphics drivers and thus you should be able to proceed with the installation, which I'd guess is the cause.

If there are any messages on the screen (and not just completely black), they could be helpful.

Thanks for the tip!

I was able to solve the problem with a USB C to HDMI adapter.

Is it possible to switch the graphics card from the CPU to a VM?
The "nomodeset" command line option does the trick, after using it i was able to install Proxmox VE 8 on the machine successfully.

Frankly speaking: after doing some tests with this pretty little box, i'm not so happy with it. Even in idle the fan kicks in frequently and under load the fan runs continuously audible (sounds like Laptop blowers under load). Sensor data shows around 70 °C cpu temp at idle and thermal imaging measures 47 °C on die tip of the blower exhaust (at room temperature around 20 °C). Even this might seem not so bad, it is in relation to the tiny package size. I doubt there is a way to fix this at software/firmware level because the cooling system design is in fact too weak(/small) for the i3 N305. All in all, it's a bit of a shame because cpu performance and power consumption (measured 6 watts min, 31 watts max on the wall) makes this machine allmost a perfect Proxmox micro node candidate. If you plan to run this machine in a cold, dark spot, then you might be happy with it.

Just my two cents... ;)

Edit: add the thermal Image.
