I recently purchased the 14RU version of that rack and, while the mixer will fit within the box, the only way it does is by fully disconnecting the cabling and sliding it all the way back to get the front on, then reversing the process when you get on site to be able to plug everything in. I have contacted SoundTown and suggested that they make a deeper case, adding 3-5" to the depth for the digital boards. I have found that most digital boards (that I've worked with, at least) are about 3" deeper than analog boards.
