I've been slowly expanding my HTPC/media server into a gaming server and box for running LLMs (and possibly diffusion models?) locally for playing around with. I think it's becoming clear that the future of LLM's will be local!
My box has a Gigabyte B450M, Ryzen 2700X, 32GB RAM, Radeon 6700XT (for gaming/streaming to steam link on Linux), and an "old" Geforce GTX 1650 with a paltry 6GB of RAM for running models on. Currently it works nicely with smaller models on ollama :) and it's been fun to get it set up. Obviously, now that the software is running I could easily swap in a more modern NVidia card with little hassle!
I've also been eyeing the b450 steel legend as a more capable board for expansion than the Gigabyte board, this article gives me some confidence that it is a solid board.
