I thought about this and feel that a NAS would be best. For one reason if PC-A is trying to access PC-B and PC-B is off, well PC-A is out of luck. I am not an advocate of leaving PCs running 24/7. They would never get updated in small offices. Seen it too many times. With a NAS you can have 24/7 access. I am however going to play with the option 3 in post#8. This way I can give them a choice. I'll try that on my PCs.
Thank you all for your helping me on this. Talking with other techs makes things easier. I also learn a lot from this forum. Thanks again.
