Very good point. I left that out by mistake.
My first two choices for OS would be FreeBSD or OpenBSD. I am very
familiar with both and run a few of them on our company network doing a
variety of tasks

Just saw that one on dell. Starts at about $550. Comes with 256mb RAM.
Suggestion to upgrade more? Maybe 512 at the least, 1gb at best?
CPU is fine. Single 40gb SATA drive. should be sufficient.

Yes. That is what I originally had in mind. Assuming I have the budget
to buy two machines (hopefully I do), i would doing something very similar.

Yes. I like systrace and especially OpenBSD.

Well, we have a T-1 currently. One of my current tasks is to measure our
bandwidth usage. It definitely needs to be cutback. The CEO was very
nice in letting users "surf" freely for awhle. However, after a recent
nasty incident, the door will slam shut on that very soon. Hence, the
"go ahead" on my long awaited squid proxy server.

All Very good points and items I definitely plan on mentioning to the
"board."

Is there another plugin of some sort that works in conjunction with
squid for web content filtering? I've come across another one called
http://www.safesquid.com
I really need some type of addition to squid to filter out crap and
ensure it doesn't get on my users computers (spyware...). Since most of
our vendors websites use only IE, I am unable to switch others to
something like Firefox. So, im stuck
