This is the one I'm looking at. Should have an extra inch or so on each side, but it's just the right height at 9 3/4" (247mm). I'll have to start giving some thought to how I'll route the tubing for it. It'll be oriented the same way as in the photo, the inlet will be at the top of the rad and the outlet at the bottom, headed straight for the pump inlet.
