I can't imagine spending $48K on a home GPU server, but I did just splurge and buy a PC with an RTX 5090, specifically to hold the largest models you can fit in 32GB. It's a top of the line PC with water cooled high end CPUs, 64GB RAM, RTX 5090 for $5K. To me the jury is still out whether this was a worthwhile investment, but I do expect to use this machine for a decade. I don't run it at 100% power (it's mostly idle, except for times when I'm training or doing batch inference). It has the nice property of being blackwell generation, similar to the machines we use at work.

It just scares me to own a box that is $48K in my house, especially if it breaks, or gets stolen.
