A picture (including volt-modded X800XT):
Pumps are in a black aluminium enclosure behind the speaker.
Rad is mounted on top of the frame, fans sucking through and blowing air upwards.
Strange big 'L' shaped tube is res / airtrap which feeds the pumps using a 5/8" connection. Rest of the system is 1/2".
Front panel of PC case shows DIY fan controller (LM317 chip) allowing voltage control from 1.25 volts -> 10 volts or switching to direct power (13 volts due to overvolted PSU).
Molex on front of case (above fan controller) is connected to the X800XT and allows measurement of core (1.70 in this case) and adjustment using small blue potentiomenter.
