A thin client configuration would be your best option for this hardware. It
requires few resources on the client machines, is easy to set up, and
centrally administered (all user accounts and data are maintained on the

This is called clustering, and isn't very suitable for low-powered machines
or slow networks. A thin client configuration allows you to use these
low-powered machines by sharing the resources of a centralized server, which
is a simpler and more efficient method.
