In 2007 I put together a bunch of servers running openSUSE 10.2. They run some specialized application software that's version-dependent and is unlikely to ever be upgraded. The working network is not connected to the internet, so there's no reason to upgrade the OS.

They're full KDE installs, and openSUSE 10.2 wasn't a lightweight distribution in its day. But now, even running in VMs, UI and network response are noticeablly snappy, and are sparing of resources by modern standards.
