Thanks for the input. I finally got everything up and going last night. The 4 clients seemed to run ok on the one box. It's a 3 ghz core 2 duo with 2 gigs of ram and a nVidia 7950 GT. I have 4 gigs on the PC I just run one account on so i'll swap that over to the 4-box when am not feeling lazy.

It's going to take a little getting used to on the controls. I need to do a lot more research on the best macros to use etc.
