WSUS is great - just be sure to allocate sufficient space for the download folder. 150-200G is plenty, and less is OK if you run the cleanups each month or so.
I have some tools on my web site that let you script the install time - particularly nice for servers as you can install updates precisely between 23:00 and 00:59 on the third Friday of every month, for example, instead of "around 11pm (+/- 20 minutes) every Friday. My tools also apply the updates repeatedly within the change window so all pre-requisite patches are installed and the server rebooted, rather than waiting for another patching session.
