I'll try to post a picture later but I'll try my best to describe it first. The loop order is pump/res-rx480-cpu-rx240
The pump/res is mounted at the bottom of the case. The rx480 is externally mounted (vertical) at the rear of the case with the inlet/outlet on top. So it's basically an uphill climb for the water. The CPU block is about 5 or so inches lower that the rx480. The rx240 is mounted vertically and occupies a few 5.25 inch drive bays with the inlet/outlet ports at the bottom. The inlet/outlet ports of the rx240 are lower relative to the CPU block and are a few inches above the ports of the ports of the res/pump.
