Re: OT - Small DNS "appliances" for remote offices.

[Mel Beckman <mel () beckman org>]

We use Mac Minis; $500 each anywhere plus $25 (!) for all the server components, dead silent, and ready to go with Bind 
installed out of the box. You can also enable dhcpd and all manner of other stock BSD services. There are "helper" GUI 
tools for the non-CLI admin built into the Server toolkit. Way fast, extremely secure, and IPv6 ready.

Yes, this hardware costs a bit more than the mini box Pcs,mbut you make up for that in reduced setup labor.
