I picked up a gateway 2000 on the swap table at the dump. I had the same model (upgraded to the max) and decided to see what the stock model was like and whatnot. After fooling a bit (and bending a cooling rod on MY gateway 2000 heatsink) I just took them apart. The cases went to the metal dumpster @ the dump and the other parts (mobos, CPUs, soundcards, modems, etc) are sitting in a box in the back room. There is a guy down the street that recycles components, so they'll be going to him real soon.
The custom build my dad made is just sitting in the back room collecting dust. The case is still in great condition.
