This mostly depends on the load on the mail, www and ftp servers.
When I ran some tests, a 486dx33 with a slow SCSI disk was able to deliver
3000 mail in an hour (this was with 1.3.x, I'd expect better perfs with 1.5).
So I guess the 2 classic could be valuable mail server if you don't need to
get/send more than a few hundred mails per hours (for the backup, and IPC
or even the vaxserver would be enouth).

I have a p100 with 32MB RAM, good UW scsi disks and a 100Mbs ethernet card as
web/ftp server (serving, amongs others, www2/
pwebstat reported loads as higth as 11000 requests per hour (I have no
cgi running, though). Again this depends on what load you expect for the
www server, but the classic can do the job.
