My suggestion is to install Windows/Linux and then get Vmware installed. You can install FreeBsd or
any other Os as a client Os using Vmware. Most people talk about buying pcs and creating a LAN
to learn about network security. Vmware allows you to create virtual networks with the various
client Os's . Currently i have a network consisting of two virtual boxes running FreeBsd and Whoppix and the host box running Xp.
