After seeing some of the wire-management jobs in this thread, I decided to go back to my case and rewire the hard drives.

I added some new holes in the back of the drive bays:



The material is even thinner than behind the motherboard. You have to be careful not to warp the edges when cutting and drilling.

I increased the size of the slot at the bottom of the drive bays when I discovered that I could run the cables to the lower hard drive under the drive cage. The top drive is reached through the smaller slot. I removed the middle horizontal bar on the bottom cage so I could run the cables to the second hard drive.



To allow the removal of the drive cages, I attached the 3-wire connector to the cage and ran a 3-wire extension wire to the fan header.



Running the CDROM, Guru, USB/1394 wires through the upper slot simplified the routing on the back of the case. I didn’t have anything planned when I added the middle slot, (accept that I never want to drill another hole it this case again.)



The USB/1394 cables route through a hole inside the top lip of the case, (I stole that idea from bjp999.) I also drilled small holes directly under the tangs that hold the top of the case on so I can remove it easily. The 4 holes on the back of the motherboard tray are for access to the mounting hardware for the after-market HSF, (not mounted at the time of the photo.)

Everything put together with the new HSF unit, (Scythe Infinity). It’s big, (and as I can now see, slightly crooked).



The Infinity is so big, that I couldn’t get the door closed with the fan attached.



I cut out a new window panel from .093” acrylic, and attached the fan with #10 nylon counter-sunk flat-head screws. It turned out that the mounting holes are perfect for tapping with #10 threads, so I didn’t need to use nuts. I was originally planning on copying the attachment system of the original window, but ended up simply cutting the window larger on the two front edges and adding notches for the screws.



Here is the fan mounted in the new lower position:



..and the whole unit in position. If not the prettiest 900, certainly the lightest.
