I see tutorials on how to install server with RAID, but not a desktop OS. Why not? What is the best work around?

You haven't said what type of RAID.
If hardware raid - you just install normally.
If software raid - the documentation
states
"If you're building a desktop then you need the "Alternate" install ISO for Ubuntu."
It provides a link to
where you'll have to follow the "Alternate Installations" section as stated in first link. The prime difference is the media used, or as stated in the documentation
2"The Alternate CD allows more advanced installation options which are not available with the standard LiveCD."
