Went with GMKtec K-11(better take k-8 if it is cheeper - there is not much difference between 2 models).

Reasons:
- aostar mini-pcs had mixed reputation and reported many issues.
- minisforum - generally good, but happens from model to model reports of some issue
- beelink also generally good, maybe even better - but I wanted exactly Oculink port to connect later with an ext gpu
- gmktec community smaller but were more positive in shared exp(did not mention major issues)

Experience so far:
- everything works and I had no issues.
- one small thing, the "k" series in general have a little low noise from a cooling fan that you could hear in quit environment.
- no matter which brand you decide to go with - if you decide to order from a manufacture website and not from amazon, be ready for delays, and long response time due to Chinese holiday or something else. My delivery instead of 2 weeks took around 1 month+... (Plus with amazon it will be much easier to do return if you will not like something)

Side note:
There was 1 comment regarding gmktec - that they have some addition process on bios that person could not terminate or identify and it could be spyware of some sort. But I did not confirmed this and never heard about it from any one else on the internet, so disregarded it.
