Is moving the BNCs and the battery box to the back of the board enough to
allow it (WM1 or Audio Filter) to mount cleanly in an enclosure or will
other components on the board prevent the LEDs or pots from poking the right
distance through the enclosure wall?

-----------------------------------

AF1:  
With the battery pack on the back side of the board, the highest part is the
rotary switch. You could use the nut on the threaded bushing on the switch
to mount one end to a front panel. You'd want to support it at the other
end. Of course, there are four holes in the corners of the PC board for
mounting screws, etc. 

Pots with long shafts are provided so the knobs are all about the same
height above the board. 

BTW, check out the last page of the AF1 manual at www.elecraft.com under
Manuals and Downloads. The response plots are quite impressive! There's a
low-pass filter and a bandpass filter. When in bandpass mode, the low pass
filter can be adjusted to further improve the high-frequency attenuation
above the passband. 

WM1:
With the battery pack on the back of the board, the highest part is the data
jack at 12mm. Next are the electrolytics at 10 mm. Mounted directly on the
board, the top of LED's are at 8 mm. One way to handle that would be to
provide cutouts in the enclosure so the FORWARD POWER, SWR and RANGE LEDs
just below them are visible. A bit of clear plastic would seal the enclosure
to keep dust, dirt and rain out as well.
