Someone else will have to comment.

^^^^^^^
For serious work go with true parity RAM and set the motherboard up to
do error correction (I assume that the ASUS board can do this; I think I
have seen postings to that effect).

Are you going to have an array of compute servers? Think about one
file server, put the big disks on it, and only ~ 1G disks on the
compute servers with just / and swap on them. Mount everything else
via NFS. Stay with SCSI everywhere, though. Evaluate the size of
swap needed. Some quantum chemistry packages may need 1G swap or
more (which should be local to the machine).

OK for file server.
Cheapest possible video and monitors, no mouse, etc on compute servers.

Only needed on one machine (file server?).

Go with a PCI SCSI controller every time.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I believe the Intel EtherExpress Pro/100B is the preferred ethernet card
de jour. (Someone will correct me if I'm wrong ;-) Think about a 100 mbps
ethernet hub connecting these puppies (bought with the money you save by not
putting 17" monitors on the compute servers). Set the file server up
with 2 ethernet cards and make it a gateway between your 100 mbps compute
array network and your campus network (probably 10 mbps).
You need a sufficiently large tape drive on the file server to back
things up (SCSI, of course).
