This is an attempt to be useful. If it is inappropriate, someone can take it down.
We have a 12-computer network that is connected to a 75-computer network - all individual doctors and staff, not a doctors group. I have never purchased new computers for our network. Always used. I get a computer, plus the operating system, for less than the cost of the operating system (roughly $250 - $350 per computer). First group of used computers lasted about eight years. They would have continued being useful, but they were Win2000 and I needed WinXP. Have had the used WinXP computers for about 3 years, and am getting ready to replace them with newer used computers that have multi-core and Win7 - because we will be upgrading to a Win SQL-Server-based practice management system that benefits from multi-core. (Our dinosaur billing software will not be upgraded to print to the new CMS Form come April 1.)
For those who have WinXP and would like Win7 for HIPAA compliance, this might be an inexpensive way to make the switch. I am using the Dell Optiplex 745 - so that is the page I am linking to here. You can back up to the home page and explore other stuff if you want. They have a huge warehouse just south of Los Angeles. I picked up my computers in person, but they will ship to wherever you are.

If you are curious about the practice management system, here is the link. We are not getting the EMR, so we will shell out around $7,000. Full system is around $15,000, but EMR and Practice Management share a single database. And it has pop-up notes, which we need due to the complexity of our billing (labs and radiology, etc.)
