Need some help with choosing my hardware - Storage, Immich and Home Assistant VM.

[Woopzys]

I'm still very new to this, my only previous built was my desktop. Now I want to built a NAS. As I don't have hardware laying around, I need to be certain of what I need before buying stuff.

For now, my use case would be running HA vm (requirements: 2 cores, 2 GB memory, 32GB storage), Immich (recommended: 4 cores, 8 GB memory) on HexOS (2 cores, 8GB memory, 16GB bootdrive).

So for my cpu: adding the above requirements gives me 8 cores, as it quite likely I'll self-host more stuff in the future, doubling that core count sounds precautious. I didn't find any reasonably priced 1851 mobo's with plenty sata 600 so 1700 socket it is. Are the 13th and 14th gen still a no go? Because a  i7 14700 is cheaper than a i9 12900K for more cores (20 vs 16).

Anyways, this is the list of components I'm thinking of buying.

Could I get some feedback?
