48 servers at 60K also does not math to me at all. Even if I consider the second-hand ones, I could hardly find zen4 under ~10K. And this is without GPUs.

Yeah, this guy doesn't know what he's talking about. I buy hardware and transit, so I know he's just making up numbers.

The numbers were really too good to be true but there's always a chance that there may be something I am not seeing correctly so I wanted to give the benefit of the doubt. Otherwise, the idea is not too crazy regardless of much higher input costs.
