The remote display is simple, but tedious.  I unsoldered the LED's from the 
regs and replaced them with 2 pin headers.  I then drilled 13 pairs of 
holes in a piece of aluminum angle and installed all the LED's there 
(actually, I used new LED's so they would have long leads).  I soldered a 
piece of 4 conductor phone cable to each pair of LED's, ran it to the 
appropriate reg, and put a pair of 2 pin plugs on the end.
Of course I also had to re-adjust all the regs.

It would probably be better to use regs with external loads, and put the 
loads somewhere where a fan can blow on them.  Of course this would mean a 
BUNCH more wires running around.... I used the internal load version, and 
have found that there are a few regs that could use more airflow.  I'm 
thinking of getting a bunch of those tiny CPU fans (old 486 ones are cheap) 
and installing one on each reg.
