Figured I'd document this...
Was doing some digging in the Deus Ex game files to see if I can get the UI textures. This is a for a future project where I want to create a CSS theme using them.
The process was a bit annoying to find them so here's a gist that includes steps on how to export the .tga files and then convert them to .png files using the script provided!

Bonus: Some pictures of the Deus Ex dev team I found in the converted directory!
