Ollama Server Component Recommendations (piefed.blahaj.zone)

I'm looking to build a low-end ollama LLM server to improve home assistant voice control, Immich image recognition and a few other services. With the current cost of hardware components like memory, I'm looking to build something small, but somewhat expandable.

I have an old micro-atx form factor computer that I'm thinking will be a good option to upgrade. I'd love recommendations on motherboards, processors, and video card combos that would likely be compatible and sufficient to run a decent server while keeping costs lower, basically, the best bang for the buck. I have a couple of M.2 SSDs I can re-purpose. Would prefer the motherboard has 2.5Gbit Ethernet, but otherwise I'm open.

Also recommendations on sites to purchase good quality memory at reasonable prices that ship to the US. I'd be willing to look at lightly used components, too.

Any advice on any of these topics would be greatly appreciated. The advice I've found has all been out of date especially with crypto fading so video cards are not as expensive, but LLM data centers eating up and reserving memory before it's even manufactured.

Definitely not needing something that high-end. It's just me and maybe one other person using it periodically for voice commands that needs to be realtime. The rest is background processed stuff like Immich image recognition and Jellyfin audio/video processing. Nothing fancy is needed. I mention motherboard because the system I'm thinking of using is currently running Plex which I'm in the process of replacing with Jellyfin on my Kubernetes cluster of minipcs and Raspberry pis that runs most of my stuff pretty well, but could benefit from dedicated LLM/ML. So, that machine will be freed up, but it's nearly a decade old and not up to the task as it is.

As for specific budget, I don't have specifics in mind. My Kubernetes cluster is super energy efficient since it's all small systems that only spin up when needed. So thinking about overall cost of ownership vs benefit. Having something too high end would just waste energy as well as the initial investment.

You could consider something from the Radxa Rock 5 series.
