Availability may be less of an issue in an hobbyist environment. Access 
to commonly used data from multiple nodes (different architectures, 
different OS versions) may be more important.

A failing quorum disk may affect the cluster, regardless of it being a 
system disk or not at the same time. How much the cluster is affected 
depends on the number of additional nodes.
