To be honest I wasn't aware of how big this rack really is when I ordered it, but I'm glad I did. There is plenty of room in this, and even though there are different depths for the front and back rows there havent been any problems with fitting modules in it.
Its sturdy and quite well built. Plenty of bolts to attach a large number of modules.
The back row has a depth of 40mm (but you can squeeze in deeper modules between the sockets) and the front row has a varying depth up to 65mm. All of my Doepfer modules fit, and Behringer told me that all their current and coming modules will fit inside both rows. They also measure depth from behind the front plate unlike some other manufacturers that measure from the front.
Cons: The edges of the rack have a small protrusion on them on the inside with makes it hard to mount certain modules pressed up against the sides, there is a small gap due to cables/components pressing against this small protrusion. This leaves a <1mm gap. MIght be an issue might not. However all the behringer modules fit nice and snugly against the edge, just certain other modules that don't fit snugly.
Pros: It big, its quite roomy, and a lot of connectors for modules. looks good standing up or laying down. And the price!!!
