Mine's pretty minimalistic.

On an ultrawide now, but still the same setup. Enemy list on right of central bars.
Focus in line and left of Target.
My cast bar in line with Focus cast bar, above Target and Target cast bar.
My status bar above abilities and just below, item by item, Target status bar.
Unless I need to read the chat window, it, too, is usually off.
All job-swap and auxiliary bars are on a fly-out command via one of the less handy buttons on my MMO mouse. I click what I want, then close it again.
My other HUD puts the enemy list and party list nearer to each other on the left while shuffling abilities further to the right, with the most important to track being leftmost rather than topmost.
