Sincere question: Is installing and running a mini split actually cheaper than racking them in a colo, or paying for time on one of the GPU cloud providers?

Regardless, I can understand the hobby value of running that kind of rig at home.

I personally haven’t done the calculation. I have rented colo space before and they are usually quite stingy on power. The other issue is, there’s a certain element to having GPUs around 24/7/365 to play with that I feel is fundamentally different than running it on a Cloud Provider. You’re not stressing out about every hour it’s running. I think in the long run (2yr+) it will be cheaper, and then you can swap in the latest and greatest GPU without any additional infrastructure cost.
