Closer to ~$30K if I had to guess. A 256 version is $11,299.00 (2TB SSD, 256GB RAM, 36-core CPU, 80‑core GPU), so yeah, 4 of those would be close to $50K but the 96->256 RAM upgrade is $4K, if we assume 512 will be double that it's ~$15K/ea.

But yes, still a massive amount of money and that's before we know the TPS or any other stats.

The closest equivalent to something like that is a GB300 based workstation, those go from 90K and up.
