Aren't people are "constrained" by the number of PCI-E slots when mining with GPU's too? I can't see much of a thermal issue with ASIC based PCI-E boards, nowhere near as much of a challenge as GPU's in a gaming machine. Where do you see the issue with spacing when you consider double-spaced GPU's?

I agree with the "professional" miners desire for scalable kit. I put PCI-E in their solely down to the fact that there are thousands of miners with PCI-E GPU's sucking wattage right now that a PCI-E ASIC could directly replace.

Yes, agreed a standalone would replace all kit surplus to the GPU also.

I don't think there would be that much of a consumer demand for rack mount kit to make it a viable commercial option for anybody though? Maybe that's another topic.


I suppose in a perfect rack mount world PCI-E could be scalable and realistic if somebody designed an embedded ARM based main-board with say 8 PCI-E slots. The PCI-E boards could get replaced just as GPU's do at present when newer generation ASIC's are produced. In a perfect make believe world of course.
