Hetzner will also rent you 768 GB of RAM with a Blackwell 6000 Max Q GPU for €2300/month [1].
Yes, it's a boatload of cash, but that's a €13,000 GPU and €20,000 of RAM at present prices. There is a segment of businesses where a fixed €28k/year bill is going to be preferred over plonking down €40k for a (theoretically) depreciating asset and ongoing colocation costs.
Renting something at a rate that'd be purchased in less than 2 years seems very myopic to me. And yeah it depreciates, but not to zero. So if you're speaking of the breakeven point after liquidation, you're probably there in well under a year at those rental prices.

And yet basically all AWS customers are doing exactly that. Turns out that making CAPEX "someone else's problem" is worth quite a lot to many businesses
