The groundbreaking part is that the full model, r1, which is as good as chat gpt, the 671B model can be run locally on very cheap hardware.
You can't run it on a random pc, but with a homeserver where you get 200-500 gbs of ram in, you can run it.
You can buy such a machine for 2-3k used, or build it new for 5k. You are 100% wrong.

Motherboard: Gigabyte MZ73-LM0 or MZ73-LM1. We want 2 EPYC sockets to get a massive 24 channels of DDR5 RAM to max out that memory size and bandwidth.
CPU: 2x any AMD EPYC 9004 or 9005 CPU. LLM generation is bottlenecked by memory bandwidth, so you don't need a top-end one. Get the 9115 or even the 9015 if you really want to cut costs.
RAM: This is the big one. We are going to need 768GB (to fit the model) across 24 RAM channels (to get the bandwidth to run it fast enough). That means 24 x 32GB DDR5-RDIMM modules. Example kits:

Case: You can fit this in a standard tower case, but make sure it has screw mounts for a full server motherboard, which most consumer cases won't. The Enthoo Pro 2 Server will take this motherboard.
PSU: The power use of this system is surprisingly low! (<400W) However, you will need lots of CPU power cables for 2 EPYC CPUs. The Corsair HX1000i has enough, but you might be able to find a cheaper option: https://www.corsair.com/us/en/p/psu/cp-9020259-na/hx1000i-fully-modular-ultra-low-noise-platinum-atx-1000-watt-pc-power-supply-cp-9020259-na
Heatsink: This is a tricky bit. AMD EPYC is socket SP5, and most heatsinks for SP5 assume you have a 2U/4U server blade, which we don't for this build. You probably have to go to Ebay/Aliexpress for this. I can vouch for this one: https://www.ebay.com/itm/226499280220
Total cost: $6,000
