As you mentioned I ditched the 14th gen and went newer. I got a Ultra 7 265k combined with MSI Pro Z890-P Wifi.(most 14th gen motherboards were unavailable and this new setup was almost the same price)
Same RAM as mentioned before. Since there is a lack of sata on the MB, I also got a LSI SAS 9300-16i in IT mode.
It al seems to be working as it should.
I did have to start all over again with Hexos. After importing my pool it recognized all apps however they didn't respond good. Apps won't stop or start on command.
A Intel X550-T2 is also on the way to make full use of my internet connection.
As for the use it will mostly be a media server with immich, plex, all the arr's.
When I move to my new place I will also try to setup home assistant.
