Nothing fancy, just bought a motherboard from SM, and a 4U case. I have a couple of boxes with 6 NVIDIA 3080s and recently upgraded to a used super micro with 8 A100s
Colocation wise, you pretty much buy the space, show up with the server and rack it yourself into a locked cabinet, not much else
That is sick, I wanna build out something of a similar size (sans gpus). How much does colocation cost in your area?
