Just mulling over the water loop design..
First candidate:
In the manual I read the 'recommended air flow' for watercooling, but it's assuming a 240mm rad on the rear, so wants to exhaust the heat, but I'm thinking of no rad there and make that an intake, draw in cool air from there and the bottom, drag it across the VRMs and motherboard, and exhaust via 2 x 360 rads on the top/side.. I can use a magnetic filter cut to size to filter the rear as an intake.
Reservoir wise, it's a shame, but the ideal would be effectively a 360mm rad on the side with an EK FLT120 D5 Pump/Res combo, as the reservoir/pump combo is the size of a 120mm fan, I don't think it'll fit with the rad header tank.. but I might squeeze a Corsair Hydro X Series XD3 pump/res combo as that is smaller than a 120mm fan.
So I think..
Bottom - 3 x 120 intake fans
Rear - 2 x 120 Intake Fans
Top - 3 x 120 Exhaust Fans through a 360 Rad
Side - 3 x 120 Exhaust Fans through a 360 Rad + EK FLT Pump/Reservoir or Corsair XD3
I am determined to not have an ugly large reservoir this time, I have 2 traditional cylinder style D5 pump/res combo's but they block air flow, and a distro plate will cover up fan spaces, so ruins air flow..
