Not a great fit. Something like Ampere altra is better as it gives you 80 cores and much more memory which better fits a server. A server benefits more from lots of weaker cores than a few strong cores. The M1 is an awesome desktop/laptop chip and possibly great for HPC, but not for servers.

What might be more interesting is to see powerful gaming rigs built around the these chips. They could have build a kickass game console with these chips.
