Though there are many benefits to running gateway services through a
Linux system, for the past couple years I've opted for an inexpensive
wireless router that has been properly secured. It came down to power
utilization as the Linux machine used about 10 times as much power as
the dedicated router.

As to benefits, I do run a Squid proxy server on my network. My
internet connection is not the fastest and I've seen pretty good cache
hit percentage (hovering near 30%-50%).

Yes, certainly.  However, there are some benefits to running a full
nameserver especially if you have any wireless devices that may need
to use printers, file servers, etc.. For example, I can connect a
wireless laptop and print to HPLaser1 or access the fileshare as
\\fileserver\. When I change the fileserver it's a simple matter of
pointing my alias over to the new server.
