Lunchbox-style PC needed

I need a period-appropriate PC to run Windows 95. I don't want to do it in Virtualbox. A high-end 486DX or early Pentium would be good. I would like a "lunchbox" system, so it's all-in-one, but not a laptop because of unreliable batteries and chargers. Not looking to do a restoration so I want something that works as-is. Absolute must is a serial port. Ping me off-list (evan@snarc.net) if you have something available that meets my needs.
