I have a kiosk PC available, the screen is a 10.4" ELO Touch Panel, the PC is a Celeron 1.3GHz with 256mb RAM. It has three serial ports, one parallel, onboard ethernet and a riser slot where you can have two PCI cards. There are also headers for USB and other devices on the motherboard. It all runs of a single ATX power supply (screen too).
Open to trades / negotiation.
