RAM is so cheap there's no real reason not to max out, or get at least 1
or 2 GB.

SCSI vs. ATAPI: depends on the work load. A normal web server shouldn't
be hitting the disk much at all once it's been up for a while; all the
files should be in the kernel's cache in RAM. And you'll have plenty of
RAM, right? A database server should also ideally have the entire
database in RAM, if you can afford it, but of course you'll want fast
writes. Spreading the load over a SCSI RAID is a good idea here. Getting
the stripe size right for your database is one of the big performance

As has been mentioned, you can always put DB and web server on different
machines if your project grows that large.
