Sorry for long absence, I was reeealy busy 
Yes, I’m really happy with this configuration as it will probably have future support for new processors series. It’s easy extensible, painless (e.g. no nvidia), maybe not the best for now but in reasonable price. That’s also why I chose it.
If you are audiophile only bad thing is DAC. I could hear difference comparing to just hifiberry! so yeah… If you’re going to listen music in good quality you should buy external DAC.
Well, there are no problems without workaround as mentioned above. I couldn’t boot it in UEFI mode (so just changed to BIOS) and sys-usb needs to be created after install as not supporting PCI reset breaks installation if you do it automatically before first access to qubes.
Another good thing is speed. OS Booting up is slightly faster than e.g my TP500LAB
But the best thing is appVM boot time. It’s only 6 seconds! (Comparing to TP500LAB 10-20, I don’t remember precisely) then app in appVM starts immediately.
(I have m2 disk 32 gigs of ram and ryzen 7 3800x)
Have you ever tried Qubes before or do you know its construction (appVM etc.)? If not I’ll try to explain it more precisely.
If you have any questions, just mark me somehow, so I’ll get notification.
