That sounds nice, but I don't see a RAID-5 controller with a hotswap 
chassis in my future. ;)

I should have mentioned, the down time is not the issue.  It doesn't 
matter if the machine is down for weeks.  I just don't want to have to 
spend more time than is absolutely required to bring the machine back up.
