Size
First ask yourself "How large will my system become?" It is not
always possible to clearly know this in advance, because building a modular
synth is highly addictive. Still, make a guess. Another way to phrase this might
be "How much room am I willing to devote to a modular synth?"
Expandability
Next, consider how gracefully your system will expand. If it will encompass
more than one cabinet, how will it grow? Some case designs lend themselves to
adding cabinets more than others. Also, it may not make sense to put everything
into one giant cabinet when you are starting out with just a few modules - you
may look at a mostly empty case for a long time as your system grows. If you
build too
small of a case, you'll have too many modules to fit into it by the time it's
done (I have done this!) If your system will have multiple cases, you must decide on your power
supply scheme - independent power supplies in every cabinet, or a centralized
large supply distributed between cabinets. See my power supply
page for more details on that topic.
Function
What are you going to do with this system? Is it for studio use only, thus moved
seldom? Or will you be gigging with it?
Ergonomics
The MOTM modules are famed for their great feel and ergonomics. If you design
a large system, how will you reach everything to patch it? How long do the rows
need to be to put all the modules together that you plan to install next to each
other? You should draw LOTS of panel diagrams of your proposed system. Look at convenience
of patch routing for common patches. Put commonly used resources like mults and
mixers in central locations where they can be reached easily. These
considerations end up influencing the width of rows and the number of columns in
your case design.

Rackmounting Advantages: Buy a rack, buy some rails, and you're
done. Portable and roadworthy for gigging unless it grows too large. Disadvantages: Only 10U wide. Vertical format doesn't
work well for large systems. Not particularly pretty.

The 'VCS-3 angled layout' Advantages: Compact, handsome, ergonomic.
Good for small to medium sized systems. Disadvantages: Cannot easily scale to large
systems. Requires a decent degree of cabinetry skill to build.

The 'Moog 3P layout' Advantages: Portable. Easy to build. Scales
easily with extra
side cabinets. Good for medium sized systems. Disadvantages: Will scale to large
systems, but you may end up with lots of cabinets.

The 'modified 3P layout'
Ken Elhardt and Ken Tkacs have designed cases which add an ergonomic twist
to the basic Moog 3P layout.

The 'horizontal layout' I built this 26U x 10U case but
outgrew it before it was ever used. Advantages: Holds a lot. Easy to build. Scales well with a second
top cabinet.
Good for medium to large sized systems. Disadvantages: Not very portable. Requires a larger power supply.
Plain looking.

The 'Moog 3C layout'
Advantages: Holds a lot. Scales well with added upper cabinets. Classic look.
Disadvantages: Not easily portable. Requires a larger power supply. Angled bottom cabinet requires extra skill to build. Modules in top rows are a bit of a reach.

The 'angled U layout' Advantages: Holds a lot. Scales well with additional cabinets.
Good for medium to large sized systems. Ergonomic top row access. Cool looking. I chose this as the basis for my own case design. Disadvantages: Not easily portable.
Requires a larger power supply. Hard to build.
