It supports DDR4 if you buy a motherboard that supports DDR4 too.

I would probably go Intel with iGPU for the transcoding and acceleration for Immich. i3-14100 is fast and cheap.

Otherwise you definitely have far more CPU power than you’ll need for those apps so no worries there.

Have you checked while it’s running all the ML tasks on import? Mine uses a good chunk of RAM while that’s running.

Delta chat seems pretty good, you can easily self host and it’s very lightweight.

I do not recommend matrix, the apps aren’t great, and hosting is a lot to deal with.
