Try adding custom attributes to the machine's ClassAd.   For example, in 
node3's condor_config file, add these lines:

NODE3=TRUE
STARTD_EXPRS=NODE3

In your job's submit file, add NODE3 to the "Requirements=" line.  
Condor should automatically try scheduling that job on the only machine 
with the NODE3 attribute.
