Comment 128 for bug 930447

"The Xubuntu 12.04 unlike Ubuntu 12.04 from what I think I read was supported for only 18 months."

Actually Xubuntu 12.04 is supported for 3 years, likewise with Ubuntu Studio 12.04.

Ubuntu, Edubuntu, and Kubuntu 12.04 are all supported for 5 years.

Lubuntu 12.04 is only supported for 18 months.

Mythbuntu 12.04 is less clear, quote from the release notes; "Mythbuntu is now supported on an LTS cycle. This means you should continue to have updates available all the way through the next LTS, currently slated to be 14.04."

The Xubuntu and Lubuntu 12.04 live and alternate images are non-PAE, and an alternate iso can also be used to perform a CLI install quite similar to the mini.iso.
