Snap to most of that apart from the slaved x axis...oh and the spindle.

I saw this Aluminium 120mm Radiator for PC or CNC Cooling. G1/4" Fitting | eBay cute little radiator on eBay and was thinking of getting it as I might put a water cooling mount on my machine for my spindle to cool the bearing housing down as I can see it getting quite hot. I've got a spare 120mm 24V fan to mount to it and would "borrow" some tubing and fittings from work to connect it all up.
