I did try with an EK crossflow but unfortunately that didn't fit, it was too long.. so i sent them back. I also tried with a HWLabs GTS crossflow and while that fit, it looked wonky in my eyes when in the case (perhaps having 120mm fans mixed with 140mm looks a bit odd), so i'm working on 3x GTX level 420's. This will also be tight in terms of fittings so will have to get creative here.
Would've loved to make the side radiator push pull, but even with the fans used (D30 in front, P14 slim rear), it is super tight bordering impossible.
In hindsight, i should've uploaded pics here for reference for the rest of you but forgot.
