Assuming that you mean "they" to be Marshall, I dont think so. You could have a 19 inch panel made to fit the Powerbrake, just be SURE that you allow for adequate ventilation. Add a fan or two next to the front and power fans off of your rack power source. Check voltages, power requirements of fan of course. I use a PB occaisionally and have in the past fabricated all kinds of crap to fit in a standard rack. (I love sayin RACK). Peace.
