[AccessD] Raid controller

Hi John,

What kind of box are you hosting the disks in, seven disks is quite a few,
especially if you have a CD drive or two also.

Do you have a seperate tower just for disks?  or does your existing case
have enough space?

Congrats on the controller and disks, sounds great,


Mark
