I mean, even Apple can't match the markups nVidia has right now. If you break a GPU in your compute server, you wait months for a replacement, and the part is sent back if you can't replace it in five days.
Enterprise offerings tend to differ. You can get a replacement NVIDIA GPU via a partner, like Lenovo, in 2-3 weeks. And that's on the high side for some support contracts.
Crazy times.
