Below is a quick mockup of a module support top panel. This would support four individual modules or a single large module. If a large module would interfere with any of the supports, that support could be clipped off.
The blue area is recessed. An adhesive backed panel could be placed here to customize the device. The sticker would be similar to the sticker on the T400.
