I think so, the divider looks like you can attach a controller card to each side. I just don't get why it looks like there are 4 Ethernet openings between the fans (looks like they've upgraded to 140mm fans). I'm also curious what type of cooling kit will be offered? I don't think the C1 cooling kit will be enough to cool it. Or will it be the big kit and that will be enough to cool 2 of these?
EDIT: I see now, 4 controller cards (do the other ports not work on the S5 controller card then, shouldn't you only need 2 of these with 4 S5's?), 2 on each side of the divider, equal to 4 S5's (8 blades/boards) or that was the original design, so yes it's probably one of the big radiator kits for each of these since it's 2400 watts.
Actually 2 of 4 Ethernet openings will be used,previous controller could only support two hash boards,but now hardware have updated,every controller could support four.We just consider that some people already have S5,and want to modify it to watercooling,and we prepare 4 Ethernet openings in case that their hardware couldn't update.
C1 watercooling kits could be used.Both sides need to be installed fans,and this modified miner need two kits.
