It depends in part on the amount of protection you can install on the computer itself.
You could also consider loading Linux or one of the BSD's onto the systems -- if all you need is a browser and a graphics interface, then you should be able to come up with a fairly small and fairly secure BSD configuration.
If you cannot impliment sufficient physical controls or it is not practical to use 2000 or XP or Linux/BSD/Unix, then you need to take the problem one or more hops away, to a router or firewall. A number of people are reporting good successes with taking old PCs, loading BSD on to them, installing two NICs, and making the device into a firewall. Such a thing would not pass muster in an environment that demands a certified firewall (e.g., a place that deals with medical data), but for your application it should work fine.
