I spent around 6 hours working on this thing today. I decided it was time to get comfortable using a dremel.
First, I decided to cut out the plastic covering the PSU. The jigsaw would have been better for this; the dremel spins too fast and melts the plastic.
I also decided to modify the original trim piece instead of using the Laser Hive one.
I drilled out the rivets for the shelf that supported the ZIP drive and the optical drive because that would have been in the way of the radiator
I didn't want to get rid of this completely because I'm going to need it for something later on so I had to make some modifications.
While the shelf is out, I figured it would be a good time to clean this up
I drilled new holes for the optical drive shelf so it would sit below the radiator (I hope my measurements were correct...)
It used to sit just below the bottom of the PSU opening
I decided I wanted to keep a 3.5" bay in there instead of making another 2.5" caddy
Cable management hole for the 3.5" hard drive
Unfortunately that bracket doesn't sit square. I messed up when drilling the hole for the screw.
I went back to the rear trim piece and cleaned that up a bit with a file and a sanding drum on the dremel
Almost forgot to cut this out
The reason I moved the 3.5" hard drive to the side panel is so I could add a fan at the bottom
I forgot to take a photo but I drilled holes to mount the fan to the side panel instead of the bracket it used to be on
Hard drive mounted
Hopefully this will look better when painted
You can see how far down I moved the shelf. It used to touch the bottom of the PSU
I cut out some pieces from the section I cut out and epoxied them to the IO trim piece. I'll fill it with bondo when I get around to filling all the new holes in the case.
That's it for this weekend.
I was hoping I would get better temps with that fan but evidently the air doesn't go through the gap between the door and the shelf like I had hoped. It could just be the fan though, it's the original fan that was in it when it was a G4. Also, as this mod goes on I'm getting closer to the real Mac experience. This thing is a real pain in the ass to work with now, but I guess that comes along with trying to make something aesthetically pleasing (even though this isn't yet).
By the way, the 3.5" hard drive and fan won't be visible within the next couple updates.
