Take pcb mounted, they work everywhere with a bit of work(you need to cut two feets away for a plate mounted plate).
Or take plate mounted that work everywhere out of the box... =D
Although on this PCB all locations except the optional 1u width in the outermost column have holes for the PCB mount switches. All other locations except one pair of the optional 1u keys in the thumb cluster take switch mounted diodes as well.
All locations in the "standard" design take both PCB mount pegs and in-switch diodes.
