Nix the raid 5/scsi.

Go with a 3ware HW raid card (one of the new ones), and run two  
smallish drives to boot from in a raid1 mirror, then get four big  
fast sata disks and put those in a raid 10 (1+0, NOT 0+1) array.  Add  
a hotspare for each.

The card is about $500, the little drives should run you $60-70/ea,  
and then $150 or so for the big ones.   So about $1400 or so, and  
it'll run circles around any raid5 array.

Seriously, raid5 bites for performance.
