Bottom of the PSU-support. I think this will clean up. Going to maybe use some rustoleum after cleaning all the rusted parts in order to keep them from rusting again. Guessing I will also spray paint the rusted parts so they look better.

Removed the expansion slot bracket - had to drill out the rusted screw.

Going to try and drill the screw all the way out and re-tap. If that doesn't work (guessing the plastic will melt when I try to drill), I'll use a bolt/nut to hold that side down.
The plastic has a brass insert for the screw to go into.

Got the metal insert removed - see the hole I accidentally punched through on the left hand side - about mid-frame?

The inside of the case with the insert removed.

Now that everything is disassembled, I'll wait to post more until I am putting stuff back together.
