By now others have answered as to why the PS doesn't come on, but as  
to my setup, I used a large 5.25" full-height drive case which I had  
from when I used 4 full-height 50 Gb SCSI HD's as my server drives.   
I gave one of the cases to another person who wanted to duplicate my  
setup, but I still have 2 left, beside the one I am using.  With  
homemade brackets, these cases can hold four 3 1/2 x 1 inch high  
drives.  Of course the built-in PS can handle the load, but some Y  
power connectors were required to power all 4 drives.  This setup has  
been working great since I put it together about a month ago.

Just a message from Doug...
