Well, we're in farm country, The houses are 70' from the edge of the
road. Our nearest neighbour is across the street: 70' + 70' + 40' =
170' to their front door plus however far to their microwave and PC. It
is a factor over which I have little controll. I do have control over
my own server.

With a head ache, of course.

It will be a few years.

I write this sitting at a Digital VT 520.
Right. Its ancient, mid-1990's technology for which I am looking. One
that will take the memory and drives to handle today's software and
data-set size. Unfortunatly, that was during the shift from propriatary
busses to standardization on PCI. For example, by the time IBM RS/6000
PPC boxes used PCI, they were just over 200 MHz. They were nice looking
boxes, able to keep three PCI busses busy: two full scsi busses feeding
two gigabit networks while running around 300 MHz with 4 PPCs. They
still command a high price. I've never heard of anyone having one die
Ron, what other ancient hardware do you remember that may be suitable.
I can browse eBay, search eg: "166 MHz -GHz" for each MHz about which I
am aware, but I can't do that for the wider Google-land. Are there big
server boxes that I am overlooking?
I'm also going to look into scsi drive holders in case I end up with a
server with few bays.
