I use this for housing a few half-rack sound modules and aside from it maybe being a bit TOO deep, I've got nothing to really complain about.
It's well built, rock solid and can take some weight without bending.
It houses a full Roland SC-8850 on the right with plenty of space still left over at the back, with a Midisport 4x4 interface on the left side and it all fits neatly without any real problems.
