Yep, and the channels strips are individually replaceable. Much more serviceable in a short space of time.
That's great for studio desks, but its hard to get the robustness you need for mobile use with all those separate little front panel pieces.
This is not true: a module holding 8 channel strips is less resistant to flex than 8 single strip modules (the panels are usually U-shaped).
The reason for multiple channel modules is economical (the cost is lower) and, sometimes more important, that you can pack more channels in the same space (there is no wasted space from the sides of the single, u-shaped panels) : if the modules are built using 1 mm thick sheet metal, you lose 2 mm (plus the necessary tolerance, plus paint thickness), let's say 3 mm each channel. Multiply this for a 64 modules frame and you lose the space for 3-4 modules. This can be important, especially when the console size is fixed by other reasons, as for rack mountable small units.
It is usually easier to fix a console built with single modules.
