Well, I chopped up the side panels and squished everything down a little to fit in 1024x768. I can't really make the panels any narrower without drawing all new health bars, so this is what you get. The chat windows are way too small now, but you can move things around to make it work out.
Have fun.
EDIT: By the way, this is only a patch of the UI. You will need to download the full UI and then unpack these files on top of it.
