The total budget was in the $900 range. The wardrobe style cabinet on the right is metal, and cost me $30 off of Craigslist. The short one holding up the big new piece of steel is made by Strong Hold, and is thick gauge steel rated for, well, pretty much whatever you want to put on it (you can put in 1,900 pounds per shelf, according to the specs).
I'm also including a big cabinet I picked up on ebay that has doors with shelves in them. It was a little banged up, but I straightened it out enough to work.

After some paint:
Here's another angle that shows the lights I built into the undersides of the cabinets. They're motion activated, made out of one of those cheap outdoor security lights.
Hammers, anyone?
