I picked up one of the  Nortel NTPB15AA (Trimble) GPSDO from 
the common auction site and decided adding a monitor display to 
the front panel would be a good idea. The entire unit draws about 
300ma at 48vdc at power up and there is room inside the case for 
a small AC power supply. There is already a switching triple output 
dc-dc converter so I'm not too worried about added noise, at least 
for my application. This will make a nice self contained package 
that I can use to supply 10Mhz to my counters. 

There is a link below to a photo of the unit with the added monitor 

to show what it looks like.
