Maybe if the front rad was a 240 instead of a 280. It's not all that apparent, but the top rad is offset to one side in order to clear the motherboard. You'd want to have the front 240 similarly offset so the ports would line up. The smaller rad would also give you some room for a tubing connection between them. Having said that, I don't really see how it'd be worth it.would it be possible to keep the atx form factor and sfx-l if you where to flip the front rad so the ports are on top, and chose the top rad with ports like below so you could put them both in parallel?
just an idea, might not be possible tho
One possibility would be to chop three of the eight expansion slots, and then have the SFX-L mount right at the back of the case, instead of needing to have that space for the right angle C13. That would let you use both SFX-L and an ATX motherboard with the triple rad setup, but it comes at the cost of really limiting how "ATX" this case is, with only five expansion slots. There's also no good way to make the back panel swappable between slots/SFX bracket, so it would have to be one or the other permanently.
