Motherboard Support:
^ All exposed edges have been eased, and the circle that has been cut serves 2functions: Lighten the weight of the piece, and to provide an aperture that cabling and wiring.
^ The long piece on the horizontal plane will be the top of the optical drive housing, and the piece that the motherboard-rail is going to be mounted to.
I wanted full-travel on the motherboard rail (not pictured) to go all the way to the front of the case; this facilitates inserting and extracting the motherboard.
I also did some work on the HDD caddy.
^ The small rails in the image serve the same function as the clear ones that I made for the optical drive. They will mount (mechanically) to the HDD's and the HDD's will slid "downward" into a slot in the acrylic panels.
I have several thoughts for looking the HDD's in place, but have not decided which (if any) I will use.
The horizontal structural supports are going to be made with graphite tubing with a pass-through threaded rod. I considered acrylic rod, but I the graphite rods are lighter.
...I am trying to shave as much weight as I can...
....looks like I have a bunch more sanding and polishing to do....YaY!
The HDD's should be here in a couple of days, so I will be able to finish the HDD caddy at that time, then it is on the the carbon fiber motherboard and the top exhaust fan.
