I have a Soundcraft Si Expression 3 in a Grundorf T8-MSOCSICOM32B. The case is built nice, but I regret not purchasing it with a dog house or dolly board. I built my own dolly board for it, which was really no big deal. The most frustrating part is not having a dog house. When I purchased the case I figured that with a Stagebox+MADI card, I would only typically be using 3-4 connections on the back (Power, eth, MADI1, MADI2) at a time, so a dog house would be overkill. However, without a dog house, you cannot make any of these connections while the mixer is in the case, you either have to remove it completely or I typically prop it up on the back edge of the box.
