2 Desktops
2 Laptops
1 Box running WHS (thinking of moving to a Synology box from this)
1 Printer
2 Smartphones
1 Router
2 Switches
Why? The desktops I'm not sure about anymore. They may not be replaced at the end of their life. Laptops for convenience. Printer is obvious. WHS box for backups and remote access. But the old version of WHS on it won't do a bare metal restore of Win 7 or 8 and probably not Vista, yes my wife's desktop is still on Vista ,so it will no longer fulfill a part of what I put it in place for. Backups and remote access yes.
One wireless router covers the house and the switches are for ports for the WHS box, my house alarm panel, Dish DVR and Blu-Ray player, etc.
