What hardware are you using to run local OS models?
Figured I'd ask here because I have no doubt some of you are running some pretty cool, cost effective solutions for local models. Don't doubt some have mini data centers in their closets either haha, but just looking to get a view into what fellow HN'ers are using for their day to day work.

Can't try it personally because windows, but maybe it will help you.
Note.. you can always try to pool things ( not memory, that is super hard; devices as there are more small models now that you can squeeze onto things ).
For production and an alternate dev environent I've configured and equipped a Dell PowerEdge XE7745 server that holds 8 NVIDIA RTX Pro 6000 GPUs. Again, running openai/gpt-oss:120b (for now)
Local LLM loaded: Qwen 3.8 27B (qwen3.8:27b), served through Ollama.
MY SYSTEM: ASUS ROG MAXIMUS XI HERO Motherboard Intel® Core™ i9-9900K × 16 64GB DDR5 RAM RTX 3090 with 24GB VRAM
They could have financed this purchase with their yearly bonus or selling some equity that vested.
And what kind of work are you envisioning doing on them now or later, if you are not going to sell them? (Maybe even with a profit, I think.)
heavily customised agentic framework: https://github.com/connollydavid/host gets good work out of the weights
Runs Qwen3.8-27B Q4 on one GPU at ~55 tok/s. I also put MiniMax H3 on the other GPU for generating images and video, and the kids have fun with that. I use this box for all my personal leisure coding projects, but stick to bigger models over API for real work work.
I started with Ubuntu but pivoted to Fedora over the summer after a recommendation from a security engineer friend. And it is mostly easier.
Generic setup doc here: (not fully updated with GUFO): https://github.com/Selicos/AI_Tools_Public/blob/main/docs/Fe...
Key changes for other distros are how to load drivers/apps and get running. Ubuntu has a recent CVE issue but worked fine. CachyOS/etc set up for more Windows like UI and transplants was fine but not focused on the Stricx Halo setup. Although I do see close to RTX 5070 performance in most games I've tested.
I was running LM Studio and some other runtimes for ease of setup and model switching. Once you settle on a runtime and model setup you like it is easy to set it up, let it run, and manage as needed.
Last week I set up GUFO, as it targets the AMD Strix Halo hardware and is efficient for Qwen Flash Next. I could probably get the work done with Qwen 3.8 27B but I like how QFN thinks and lets me follow along. Starting at about 260k context, I see 88gb of RAM usage when loaded and about 108gb when in use, depending on context overhead. I do have to restart the model every so often as Copilot Chat in VS Code starts failing.
I have also run Lemonade, llama.cpp directly, vllm, and more. Custom or bespoke runtimes for your hardware are key, like Srata or GUFO. I need to look at llama-swap. LM Studio is easy and with their Tailscale backed link feature you can stay connected from any device.
IF it supports OpenAI/etc back end you're mostly there. Get the model running and connect from your preferred harness/etc. GUFO works well with Copilot Chat in VS Code. I need to connect it to Pi and openhands/etc later this week once I get this test project in a good spot.
Qwen 3.8 27B, Gemma 4 26B A4B variants, whisper, and more run well. A Spark or bank of GPUs would do better, of course, but not for under $3k for 128gb of memory. I have tested adding an Nvidia 3060 12gb to the Strix Halo but the iGPU is turned off by Fedora and I didn't have more time to solve.
My secondary Fedora AI system has the 3060 12gb and a 5900XT (16c/32t) plus 64gb of DDR4-3200. I need to get Strata up on it and see how well medium sized models work on the mixed memory. I bet MOE models will work well. I have the hardware so will use it but renting capacity is much cheaper if you just want to mess around and get used to the tools.
Happy to answer questions about how I got here. I'm an infra guy, not a software dev, and what I'm doing with AI at home could definitely be 5x faster with a real dev and dev process.
Even at half of today's retail price they're not remotely cost-effective compared to cloud models for my single-developer workflow, and idle power draw is quite high with the ConnectX-7 NICs powered on for clustering. (Mine idle around 45-50W each. Powering off the NICs cuts that roughly in half, but they're still very power-hungry compared to an Apple Silicon Mac or even a Framework Desktop.)
I learned a lot building the cluster, which was my main objective. I could probably sell them for a nice profit, but I'm still enjoying using them.

I'm doing a bunch of batch work for an experiment with them right now, but my daily driver is a Gemini Pro subscription.
I kinda want a Mac machine to test and publish few apps, but I can't justify 128 or 256gb budget right now.
The plan is to use it with Open WebUI, PostgreSQL with pgvector and Apache AGE, and my own database schema, and then have it be my complete second brain, running completely privately on my own hardware and always being available over Tailscale.
Since I still have 20-30 GB RAM to spare after loading that main orchestrator I will also have a coding worker that will do most of the grunt work, coordinated and commissioned by the orchestrator. For now I have readied https://huggingface.co/pyros-vault/Ornith-1.5-35B-A3B-BigBan... (a mix of Qwen 3.5 35B and BigBang) for this task.
For now I still use Codex and ChatGPT Pro 200 to do all my work, but the plan is to move over to local LLM work as soon as I have finished everything I realistically need frontier models for. Which is going to be for a little longer.
I got my first 7900xt 20gb on a good sale shortly after they came out in an open box deal on ebay for $590.
After another 7900xt 20gb popped up on facebook marketplace recently for $420, I sniped that and then got a microcenter deal on an asus proart board, 32gb of ddr5, and a 9950x for $1050.
A couple more deals for used cases, an older 1tb nvme ssd I had lying around, and a nice PSU finished the build.
I run Qwen 3.8 27b on linux and have tuned the llamma.ccp / rocm setup substantially with the help of codex and claude. I get ~80-110 tok/s depending on all kinds of factors and full 256k context windows with a 6-bit quant.
It's surprisingly capable and I love that I can run it indefinitely, tuning as it goes to behave more like a frontier model.
