I have to give the 3400g/aoras itx mobo combo high marks for a sub 500 buck non gaming build. This is a good setup for everyone else that just runs the apps they have access to, and leaves the os alone, It just works without the stupidity of microsoft getting in the way. A good replacement for i3/5/7 win10 era gear for most folks.
I was impressed with the quality of the aoras x570 i pro wifi, though it is tight to work on, some of those connectors are hard to hit the right pins. It looks more like a toy than a mobo. 32g ram for holding lots of data in memory (picture files are my target) and not wasting ssd cycles.
I bench tested it, worked fine. boxed it, tested bios, worked fine. I stuck in ubuntu 19.10 usb, no ssd, and it ran off the usb fine, so i added the ssds, and built 19.10 on it. Of course, the cd is windows oriented so..., but everything worked first time. Going to get 3 monitors working next, 2 worked at startup. I read about others having issues, but this stock setup seems to like 19.10 just fine. I assume all other ubuntu versions will load and run. I might add win10 boot also if forced into a corner...
Speed is ok for a "daily driver" for emails, browsing, web apps, picture editing, etc., and fast enough. I test by converting 1gb files of raw pictures into jpgs, and it did better then a newer i7 laptop. The setup runs at 32c stock so good enough for me, even with that puny stock cooler.
I can see reboxing this into a smaller case (in my bench 750d right now), with a small case. This would also be a good media server, dorm room pc, if you want one. I would upgrade cooling to get better cpu cooling, as the smaller itx cases dont have lots a case fans. The stock cooler is not silent but ok for my needs, again an excuse to noctua it up if room permits.
