I always knew hardware discussions on HN were below the normal standards. But sometimes I am still surprised at how low it can go.
Everyone is buying the tool that does the job, or building that tool if they want to make that large investment...
I'm updating my wiring and air conditioning for a 7x5090 workstation because having that power for experiments under the desk is worth the cost (and fire hazard).
If I had to build 10,000 of those I'd be banned by NVidia from ever buying their hardware again.
