GH200 has HBM3 memory. You cannot compare this to a RTX Pro 6000...

We build these desktops from Nvidia servers we buy from reputable manufacturers like Pegatron, Gigabyte, Asrock Rack, and many more.

H100 PCI and GH200 are two very different things. The advantages of Grace Hopper are much higher connections speeds, bandwidth and lower power consumption.

We can get around tariffs, if that is your concern.

Honestly I wasn't going to drop ~10k USD on an unknown seller that was from another country.

There is always some risk in business and life itself...
