I think that except the storage part it would be able to cope with the load 
just fine if you get rid of the Perc3/Di and us a /DC or /QC instead.

Mirror the OS as well, it's stupid to not mirror the OS drive, if you have 
to wait 4 hours for the techs to arrive that means 4 hours no server plus 
the time it takes to install an reconfigure the server.

Don't use raid 5 for the mail spool, I suggest using raid 10 instead. 
Mailservers behave much like database servers and raid 5 is very bad for 
the performance for either application.

You could use a 6x73 or 6x143 raid 10 which equals 210GB or 420GB.

And I suggest using the Perc3/QC in this combination which works reasonably 

It might just be your lucky day, if you only knew.
