Back when I used to build custom Harleys and my OCD was out of control I spent way too much time running my wiring through the frame. And those old Harleys did not have anywhere near the amount of wires that these CB 750s need just to run. Now I just run my wiring neatly and run it through heat shrink wrap. I would suggest that you go to vintageconnections.com and get one of their terminal kits with the factory style connectors and crimping tool. They work and look better then the automotive connectors you get at the autoparts.
However I would like to point out that the bike you posted a picture of is a "Show Bike" and might not even run. It is/was common to build show bikes as non functional sculptures. Often not even having internal engine parts. Since the bikes were built for show running was not of concern, and not having the heavy engine internals made the bikes that much easier to load/unload and move around.
Hiding all the electrical components under the tank does sound neat, but there is not much room between the tank and frame, especially for a battery large enough to run the electric starter (the DOHC does not have a kickstarter, only an electric starter.) You will need to cut out a lot of the inside of the tank and reshape it for clearance. This would work, but you would not have much gas capacity for riding. One area that you might consider for the battery is the area under the front of the swing arm. By using the smallest battery possible and laying it down, you might be able to hide it under there. Also, build the bike doing all the fabrication, and then take it apart for painting. You do not want to be doing fabrication on a freshly painted frame. You might want to check out Shinyribs hackjob build thread. He went through a lot of the modifications you are wanting to do on his bike.

I like vintage bikes because they take me away from the clutter of technology that I work with everyday and back to a simpler time of mechanical elegance and simplicity.. "ninadm"

. I have a new fabricated battery box that fits under the tank and a shallow plate that sits under the seat for the fuse holder and relay. The new battery is a lithium ion, 8 cell, and is less than half the size of the original with 1/3 more cranking amps. Of all the new parts purchased, that battery was the most expensive part.
And the block under the sidestand look really weird. The rear brake pedal seems to float in a realistic place, yet it seems sorta superimposed over top of the pipe. And there don't appear to be any plug wires. Pretty bike, interesting picture.
