I believe the case is 53 cm deep (I requested the depth based on what was listed for another case they make). I haven’t had any issues with modules fitting, even over the power.
I’m using three rows of Trogotronic power. For some reason, when I had a fourth busboard, several modules, notably Three Sisters and Batumi, were very unhappy; but they are fine with three busboards.
I’m generally happy with the case. It’s supposed to close patched, but it doesn’t. Not huge concern for me, though.
