With the parts available, one can rig up almost anything, which has always been a theme of this forum. Sure the shrink-wrapped retail components are expensive, but that's because it's being sold to folks with more money than sense (I've seen guys drop $5K on a custom gaming system). It can be done more cheaply.
The point for me was, you folks were talking about problems cooling a box in a dirty environment. To me that says use heat exchangers. If you don't like liquid-to-air heat exchange, use air-to-air heat exchange. From the days I started building experimental lab equipment, my personal choice always has been to try not to generate more heat than I can conduct away to ambient. These days the drive toward ubiquitous mobile devices is solving the problem on the computer side but it's still an issue on the motor-drive side.
