[AccessD] Raid controller

Mark,

This is a Lian Li case:

http://www.newegg.com/product/product.asp?item=N82E16811112108

It has dedicated space for 12 3.5" disks down in the bottom of the case as
well as two power supplies (not included).  There is also space for SEVEN
5.25" drives up in the front of the case, forward of the motherboard.  This
case is... shall we say "large". 

I really like the case.

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
