(1) Does the NZXT Kraken X60 fit the rear right-compartment and front left-compartment locations? How about the Corsair H110? I'm particularly concerned whether the NZXT Kraken X60 fan spacing (which I think is 15mm) is the same as the D600. Are the D600 140mm fan mount holes spaced 15mm or 20mm?

(2) Does the I/O port module have one or two USB 3.0 cables to connect to the motherboard? I'm trying to determine how many motherboard USB 3.0 headers I need to connect all four I/O port USB 3.0 font-panel connections.
