My plan is to try and keep one running. However, I haven't started the running one for over a year. I don't know if everyone has seen: http://archive.is/v6ziF. It's an archive of the cooling system rebuild that someone once did. I attempted it on one of my units, unfortunately the first attempt was unsuccessful.
