Summary of my impressions with feedback so far from earlier batches. Following the Desktop forum threads closely. Hoping for shipping end of October, or more realistically around mid November.
One user experiences PSU fan noise for a minute every 10 minutes: Noisy PSU fan - #22 by m0gg
Hope it’s just something wrong in their setup or a fault in their unit. Not gonna cancel my order, as I NEED to have the form factor 
But would be a bummer if that experience was true for everyone.
Other than that mostly feedback about the PCI extension slot capabilities. Not planning on using that anyway… at least not for an external graphics card. Maybe to expand M2 slots, but two are plenty for my use case at the moment.
Wondering why the Desktop does not get official Ubuntu support.
AI on that platform + Linux in general seems to be a bit of WIP with everything working better every day. Most kinks seem to be worked out already before batch 10 ships. At least for general AI applications and prototyping. Not necessarily getting every bit of performance out. Which again is fine for me.
Overall still hyped and can’t wait to join the club.
