> There are rumors that Apple is planning a M8 based server in 2029.

The issue is that the current Apple way of designing hardware doesn't really work for servers. An individual 1U server can easily cost $50,000 or more. Soldering everything together so that if a single memory chip goes bad you have to replace the entire machine instead of that one stick is going to make customers unhappy. Likewise, they expect to be able to add storage or network ports, and expect the software to have enough openness that the new systems will work with their existing enterprise SAN or what have you.

Obviously Apple could make open server hardware, but then people might start wondering why they can't make open laptop hardware.
