|Also the useage. Do you really need a server? With a business you may need a server, especially if you are running a networked system program and need a uniform file system and back up, but with a home and some small office uses you may just need a pier to pier network run through a decent router. The desktops should be hard wired and the portable ones will need a wireless set up, but they are completely compatible and if your shared storage needs are moderate, you can add a large hard drive to one of the computers and make it a shared drive (you can do the same to another computer and set up an automatic back up to that one).|
In this situation you could use a decent router, a switch to expand the ports, and a wireless router plugged into the primary router. All internet should go through the primary router.
You have to be a little bit crazy to keep you from going insane.
