[K12OSN] New Server Capacity Thoughts.

Personally I would want to have 2 SATA drives in software RAID 1.  But 
if downtime isn't a big deal then a single drive would be ok.  If the 
system is just being used for games, then maybe downtime doesn't matter. 
  But do you think that people will start to use it for more than just 
games, and come to depend on this system?
