Thin Client for Java

I’m putting a touch screen OI at a remote site that has a vpn connection to the server that during normal operation will run the client App. But will also have a panel edition version of the app installed so local control could still be maintained in the event of a communications failure. The question is would a PC like the ASUS EeeBox that tailfire mentioned be suitable/capable of running the panel edition app or should I be looking for more horsepower. The panel edition app will be monitoring/controlling < 100 data points in the PLC.

Thanks,
