You haven't mentioned whether you plan to use SCSI or IDE drives. The
PERC RAID controller in Dell's PowerEdge's works quite well for the
former, but you might consider the 3ware twe if you're doing IDE.

Hmm. What makes you think that a journalling filesystem gains you much
when you are running a database?
Databases do their own transaction management using two-phase commit
and logfiles for rollback in case of a crash using a few very large
files, which they'll write to directly using async/directIO (whatever
the term you wish to use is), rather than using OS/filesystem
