I've been pretty happy with my Framework Desktop, though I managed to snag it before RAM prices shot through the roof. Currently, a tricked out model is around $2500.

Mine sees more use as a Steam machine, but it can run decently large models. Ollama was trivial to get working, and qwen3-coder-next spits out paragraphs of text/code in seconds. I don't really do anything with that, but it's fun to mess around with. (LLMs are still pretty bad at assembly language.)

You can buy a 128GB mainboard from framework for $2300, so maybe somewhere a bit over $9k by the time you've got power, storage, cables, racks (they sell those too). I was thinking about getting into one of these Strix Halo setups but decided to go a slightly different route with a lot higher TDP, better throughput, and a bit less VRAM.
