WTB: Inexpensive Intel box... Mini?

Hi Listers, I need to get my hands on a low-end Intel box, just for running some accounting software and other non-graphic/memory intensive applications, so it doesn't have to be a powerhouse. Need a minimum of 512MB RAM and ability to run 10.5.7 or higher. Original install discs would be a plus,
