Bloody hell!!! It's started already!!! The deliberate manufacturer's wind up, the misplacement of connectors, bleeding motherboard screws!!!
Right, mobo is in, CPU is on, Heatsink is on. Started to connect up wires, and the first one I find is an 8 pin power connector for the CPU. Only there's two. One is labelled P2, and white, the other is labelled P4 and black. Now, I thought (assumed) I would need P4, but that one won't fit, and only the white P2 connector does, even though they look identical, so I've had to use that.
Next thing... in the mobo instructions, it tells you to connect a 4 pin power connector to a socket towards the rear of the board, to power the USBs. OK, fine, but if I connect that, the other two power connectors won't reach the drives, so I won't have enough connectors for them!
