umm, quite a big monster to be running on an IDE drive... get a SCSI!

in theory it depends on how dynamic the site is really (lots of disk
access to static pages or some CGIs or a database?) but from what I
read, it's almost ALWAYS more beneficial to have SMP on such a machine.

I had a good experiance with 2.1 kernels and a dual Ppro compilation
monster we had at work (AMI motherboard), but that was a long time ago,
and 2.2 SMP is much better.

I think that was back in the 2.0 days. EEPro probably still suck. I love
my 3COMs, never had a problem with one. ever.

serious warrenty and onsite service, like any important server.

be sure to have it running an NTP daemon and synching to a UP machine,
linux SMP system clocks tend to go loopy.
