I like it. My earlier complaints about fiddling with CUPS to configure remote access to the attached printer was before I discovered "Server Admin". As you might suspect, just about everything can be done via the GUI tools without messing with CUPS and the like directly.
It's a quick, nearly silent, and unobtrusive little box that consumes hardly any power (compared to my previous dual-core Opteron box). It's hard to beat the features, especially for the price I paid ($850+ shipping and tax for a refurb from Apple).
Cheers,
Scott.
