I built a large external capacitor bank and used copper buss to connect all positive connectors in parallel and the same with negative. These were large value caps not like what you are proposing. What I would do is to get some 12awg Romex and strip out the copper wire and use that as your buss wire (don't use stranded). You layout your caps in straight line, "S" lines or whatever fits your space, then use the bare 12awg copper wire to run from the plus from cap to cap in your configuration and do the same for the negative. Don't try to get fancy with a "star" configuration as it will be more bother than it's worth. Running the 12awg from cap will work in circles, straight lines and "S"'s and in any combination. Figure what layout fits the best with the most caps and go for it.
