I'm sure they have done plenty of market research, and that research probably indicates that enthusiasts who buy server racks are a much smaller market than large enterprise users that need easily scalable on-prem resources.

Lots of people saying "I would love this" is not a profitable market. There are a lot of implicit assumptions in that phrase. Would you buy the lowest level rack for $100k, paying extra for any support? (I don't have any insight into actual pricing, but I know enterprise consumers don't bat an eyelid at prices like that.)

If not then maybe the "I would love this" is not relevant for a real market.
