    And how many of those are significantly different between the two options? Either way, you still need one or more sysadmins, you still need a backup setup.

      In my experience of managing a team of 10+ admins, less than 5% of their time was spent dealing with physical hardware and that includes installation and repair. Today's equipment is very reliable.
