it's a frankenstein (made from multiple previous computers) that runs a P166 MMX, 64 MB of RAM (maxed out the board), and has two 1 GB hard drives. I keep Windows 98 on it and keep it in the closet in case whatever my main rig is breaks down and I need to get on the internet to access drivers or order parts or whatever. I sell my main machines as I replace them, but I keep around that old thing as my backup since it's pratically worthless and gets the job done.
