I went with a 3 tone chassis. I had actually considered putting a red stripe down the middle of the white motherboard tray to simulate the center line... but never could get it to simulate properly on my test pieces, so I left it as is.



To power the tops of the puck lights, I had to run cabling down under the chassis, so I drilled a hole and fed the cables through the space behind the mobo tray.



Using a 4 post bus bar, I attached the grounds to 2 of the posts, and then used the other two posts to supply the 5v line.





I then needed a way to mate a female molex to bus bar. So I cut 4 lengths of cabling, attached 2 to the center grounds (like normal) and then I sandwiched 2 cables into a single 5v molex pin...


and installed it into the molex...


Testing to make sure I have the lines setup and feeding from the proper lines:


...and attached the molex to the power bar.


Here I mounted the bard to the back of the tray, sleeved the cables with some plastic split looming, and fed the molex out just under the hard drive bays:
