A good start but you need to find a consultant to dig out the rest of the requirements. So far any (new) machine should be fine and Linux could supply any feature you have given so far at great savings.
Time to find someone to flush it out since no one could nail this one with just that much information.
I am in the process of outfitting a small business with all new computer equiptment. I need to setup 5 or more computers on a private network that can be monitored by an administrator and also used for file transfer between the computers.
The system needs to be duplicable and easy to use, and Im not sure if I should use a networking tool such as novell or cisco or use something else. Given my needs I still need to pick out computer equiptment and run high speed data lines inside the office so any imformation on that would also be helpful. Thank You ahead of time for the advice.
