Bookshelves, an entertainment center, lots of medieval armor, several homebrew computers (I'm putting the finishing touches on an 8085 now: saundby.com), a couple of fish tanks, my computer desk, a parallelogram mount for my binoculars, several telescopes, including the primary optics.
Building is just another part of hacking. If you asked me what I'd modded, I'd have an even larger list. I originally got into electronics and computers because it was a cheaper hobby than model railroading. I couldn't afford railroading stuff from the hobby shop, but I could always find a broken radio to get parts out of for electronics projects, and make money repairing radios and TVs until I could afford a microprocessor. :)
