Fan controllers and Power switch:
Installed using the re-made spacers. One can see that I used self-tapping wood screws torqued down into pilot holes; not the ideal solution, but I'm tapped out of ideas at the moment that precluded drilling on the top panel.
The power switch is an illuminated (red) bezel type.
Trays and raw rear panel:
Test fit for the PSU (Silverstone 1200W) and the HDD rack... again...

don't wanna mess this part up.
Here are the parts for the PSU and HDD trays. The carbon fiber angles were cut down from the first batch that I made several months ago. The flat pieces are remainders from the cut-down motherboard tray and are decorative in nature not structural. The aforementioned pieces will be used on the outside of the trays to cover the capillary bond (tray to backplate) on the otherside as the backplate is bronze.
The HDD tray/rack assembly will get a 120mm fan for an exhaust directly behind the drives.
I did not get as far as I wanted since my return from abroad, but I did get to the point of cutting the rear panel to size.
OH!... and also, I dunno if I introduced you guys to my little friend:
...Hey! Don't laugh... that is 1 gallon of sheer air-blowing pwnage right there...
