Mike,
Hi. Thanks for the question. It is a lot to go over, though. First, I have to say I am confused about your imaging for updates. Generally, Java/Flash/Reader, etc. can be done very quickly and, in fact, even automatically, although I am reticent to update Java without research. Same thing with updating Windows. Again, it can be updated overnight and rebooted without any time at all, but except for a service pack, they don't take much time. It also depends whether you trust your users. Personally, I have no problem with my staff doing updates after I have done mine and approved them.
Images (in my opinion) is when you want to do a complete overhaul of a computer especially when you upgrade to a new OS. I agree with you it is much quicker, but I am not sure what you mean, though. I would never install a new version of AC and then update all the computers with an image. It is just far too dangerous as you are now making every computer the same as the one you installed AC on. Besides, the install for the server is different than the one for the clients. You can sit at a computer, using RDC and go around and install 10 computers with AC in less than 30 minutes.
I think it is great that you trial things at home. That is a really good way to keep out of trouble.
I also would try to use as many desktops as possible. Just a suggestion. Using the same computer brand is a great idea and making sure they are all specced out the same is a great idea. So Dell OptiPlex or Lenovo using an SSD with possible a large HDD for storage.
One recommendation would be to use an isolated computer for your main computer. It's not a good idea to have your main computer being used by your receptionist, etc.
Your keeping files on one computer is another great idea. Then you back that computer up and not worry about the others. Of course, this leads to a server/client setup which would be more efficient there. I can guarantee Sandeep will recommend the same.
BUT a warning here. I don't want to get into the P2P vs Server/Client argument here. I mean with the other users. They both can be used well.
Another option that way too many people do not consider is too spend some money up front and let professional networkers set it up. Just a thought, but it is very helpful.
Sandeep spent tons of time on here going over how to build computers, networking, etc. They are at the top of the General forum and on his website. He will fill in the blanks I am sure.
http://sandeep.pdstechadvisor.com/server-buying-guide-march-2013/I also agree that you should have the same OS and everything should be 64-bit.
Again, I may be misunderstanding but you want consistency and yet you have a lot of reasons why this computer should be that computer, etc.
Just some thoughts. I am sure I can come up with more as you fill in the blanks.
Good luck with your undertaking. Think it through. Write it down. Think about Uninterruptible Power Supplies. Don't use MacAfee or Symantec.
