As other people wrote, a moderate computer will do fine as the central 
manager.

If you are submitting 1000 or more jobs to run on your cluster, your bigger 
concern are your submissions points. If you have a single computer for 
submissions, it is more likely to become a bottleneck than the central 
manager. If you have multiple computers for submissions (each user submits 
from their desktop, perhaps) then it's less likely to be a problem.

Having many idle jobs in the queue isn't a problem, except that condor_q 
can be a bit slow to respond. But having 1000 running jobs submitting from 
a single computer can be the bottleneck.
