If you can do it, i would suggest that you put the gateway/firewall on a
separate box. scrounge up an old 386 or 486 (running debian, of course)
if you have to.

It's not a performance issue - a well configured debian box can easily
handle all of those tasks - it's a security issue. the fewer services
running on your firewall, the less likely it is that a newly discovered
security hole can be exploited.

something like this ought to do it:

      ^ (ISDN line to the internet)

      v

    |  386  |      | Server |
    +-------+      +--------+            (other machines)

        +------------------------------------------------------------->
            eth0 - 192.168.1.0/24 (internal, firewalled LAN)


one box *can* do the lot, but it greatly complicates the firewall and
other security configuration.

see comments below about mixing WS & Server functionality.

more memory is good.  much more important for fileserver performance than a
few extra Mhz processor speed.

PCI.

anything that works. an S3 Trio-64 is good value for money...cheap and
adequate for most needs. 

remember that this machine is primarily a server, not a workstation.
mixing those two functions is OK if the user is the system admin
and knows what they're doing (and how to avoid harming system
performance/stability)....however you can't trust a normal user to know
that they really shouldn't be playing quake or real-video on the company
file-server.

DDS-2 or DDS-3 tape.  don't bother with flimsy toys like ftape units.

PCI NE-2000 clones work well in my experience. they're not the fastest
card around, but they're dirt cheap and easy to set up.

i've had problems with 24x CD-ROM drives. didn't bother figuring out
why, i just swapped it with a W95 user for an old 8x cd-rom.
