I didn't spend that much, only $6500 AUD for a GB10 based Asus GX10 which is even slower than OPs, but I spent that because it makes for a great learning platform. Theres not much else that lets me fiddle with 128GB of RAM for my graphics processor, and it's quite lovely to be able to run things as long as I like without worrying about my cloud instance being shut down.
It's not financially a good idea: renting really does beat owning, and cloud beats both if you're only running inference on these machines. But I'm not just doing inference, and as a thing I can do silly stuff on to learn, it's hard to beat!
Spot pricing and instance availability don’t apply to on metal hosting. You’d have your own machine dedicated to your own use only, at a locked in price.
That's too small. I was quoted a machine with ~1.5TB of vram, for $10k/mo. This was the minimum node size in the AI data center I was talking with -- they don't make smaller nodes that you can lease as bare metal. There is no public pricing though, and you had to know people to get in.
