That's easy because no matter what IT hardware you bought, it's worth more now than it was two years ago. That's something that's unprecedented, never happened before, and as soon as we get flood gates open on ram manufacturing OR when the AI bubble pops, all IT HW deprecation norms will return and making a profit by buying something IT will vanish.

I had a GPU server four years ago. Had I not sold it like three years ago with 2x price I bought it, it would be likely something like 5x the price nowadays.

I really really miss filling my home rack with old enterprise stuff. All I want is this hardware winter to end.
