If there's a second housing bolted on the top that contains a cooling fan (not likely), you can probably remove it and use liquid cooling, which will save you some length, as well.

Or outside cooling fan like Netgain uses. I've worked as a machinist for 37 years and could possibly do it, but to me that would be an expensive experiment.
