There was at least one company that lost everyone's data - they used
non-enterprise grade stuff.

Curtis, that is a great post, but i don't see how the harddrives are
kept cool.  Many drives have temp gauges so would like to see how hot
it gets in between - they are packed tight.

$5/month/pc/unlimited is a smokin deal.
Servers run Debian 4, but didn't see a Linux client package.
3 drives / 15 failure capability  --- hmmm.
