A good linux server will suffice. 6500s have a pretty wimpy CPU. This is from a linux server with a cheap atom board:
assID=0 status=06f4 leap_none, sync_ntp, 15 events, event_peer/strat_chg, version="ntpd 4.2.2p1@1.1570-o Fri Nov 18 13:21:21 UTC 2011 (1)", processor="x86_64", system="Linux/2.6.18-274.7.1.el5", leap=00, stratum=2, precision=-20, rootdelay=50.667, rootdispersion=30.974, peer=51016, refid=xxx.xx.xx.xx, reftime=d38fc77c.8a8b6adb Fri, Jun 22 2012 22:41:32.541, poll=10, clock=d38fcb62.931af16d Fri, Jun 22 2012 22:58:10.574, state=4, offset=0.538, frequency=-11.308, jitter=0.195, noise=0.396, stability=0.001, tai=0 Most of the dispersion and jitter is related to latency. Your results may vary but a number of Stratum 2 servers will help stabilize the server. You should have three NTP servers in your environment to provide failure and inaccuracy resistance.

I am in an enterprise environment. We have also considered using a couple of my 6500s but my gut tells me that is not a good thing (tm). We will be getting a stratum 1 feed from a local datacenter provider - and was looking at the various NTP boxes around - many of which with the ability to take a GSM clock source. Any thoughts on which one of these is stable?
