Can you share the costs of the (home) machine that you created?

Let me get back to you on that. I didn't buy anything specifically for this project since I already had a lot of computer parts lying around. My friend owns a 3d sculpting studio and frequently upgrades his employees computers. So when I do the upgrades I end up with all the spare parts.

My biggest recommendation is having at least 64gb of RAM and a fast 2tb NVMe drive. Apparently running a node can be cpu intensive but I think that the thread ripper might be a bit overkill.
