The only achilles I can see for an opensolaris NAS box is the power consumption cost \
for an always on server

looking at http://www.pge.com/tariffs/ERS.SHTML#ERS
It looks like 12c per KWH that come out very close to $1 per watt per year
So if you spend say $500 on a box but it consumes 200W you will
spend more on electricity over 3 years than on the hardware!
