Only software on the machines are strictly for what I am using them for. I have a router with a harddrive if I do download something and want to put it on another machine, but I don't remote desktop into them or anything. Each computer is on a separate desk, own monitor and mouse and keyboard. I just like it separate and not complicated. Keeps work stuff super focused and clean, for me. I could network them more if I wanted to, but gets the job done.
