I think the Intellijel 7U 104 should be able to handle it provided he uses the optional TPS80WMAX supply board. That sucker's rated for 3A on each 12V rail and 1.5A on the +5. While you could theoretically jam that much draw in that case, I think you'd really have to work at it to find modules that can max that amperage. Even so, I like to suggest that the P/S get majorly overspecced in any build; even if the draw is closer to the TPS30's output levels, it's still better to run the 80WMAX so it can stay cooler, loaf and last longer than heavily taxing a smaller supply.
But yeah...just use a flying bus distro cable off of one header, probably would be best for the tile row since there's not going to be significant current draws up there. As long as you can locate a flying bus with 10-pins for the modules and a 16-pin connector for the bus connection, this should be golden.
