If you’re thinking of buying a Minisforum GK41 mini PC and running Proxmox on it, I thought I’d share some info that might be helpful. I recently checked out the IOMMU groups on my GK41, and I was happy to see that the USB controllers are in separate groups.
This is actually really useful if you want to pass through USB devices to your VMs. For example, I’m thinking of using a Zigbee stick with Home Assistant, and this setup makes it possible. So, if you’re into home automation or just want to play around with virtualization, the GK41 might be a great little device to consider!
