Quark fried, blown capacitor...

Perhaps a display of ignorance, but is there a single cap solution for what we are doing here? I have six of the 35v, 330uf, low esr caps in a bank. Could I have just used one big cap? That would allow us to take advantage of the rather long leads on the cap to directly solder them to the pcb where the power leads are. I haven't seen any significant benefits to running the caps on the Quark, except that I haven't blown it up yet. The MM seemed to show great benefits, but the Quark hasn't. I'm wondering if that 1" or so of wire that I have connecting the caps is too much resistance or too long of a distance.
