That rad's an aluminum oil cooler usually found on motorcycles. I got it from Danger Den, although you might be able to get one at a local auto or motorcycle parts store. It measures 4x8" including the barbs and brackets.

I originally meant this setup to cool a K6-3, but at the last minute decided on a major upgrade. When I get another case I'm going to get a bigger radiator - probably a 5x11" stacked plate - for the Duron. What's left over will be used to cool my K6-3, which gets up to 115F at full load with a Gorb. The coolant I'm using is a 1:32 mix of distilled water and water wetter. There's no obvious signs of corrosion yet (only running 3 months) but the PVC hose has turned a brownish color. I drained the coolant and cut a small section of hose out; there are no deposits on the inside, the PVC itself has discolored.
