Finally, you don't need a super-grunty server, just as many disks as you can afford!
Amen to that. This would be why most big iron systems only ship with a very small number of surprisingly lowly clocked CPUs. I heard of one system managing a 0.5TB *active* database (ie, not just a warehouse) with only 3 processors clocked at 150Mhz.
Of course, you would end up with a lot of system time without a decent IO controller. So, best to stick with the tried and tested solutions - which means high-end SCSI or FC-AL.
And whatever you do, don't use any RAID level other than raid 1, or maybe 1+0.
