Thanks ! These are Dell GX 620's I got off eBay for about $175 ea. They are all wireless N back to the router. The printer is even wireless. Eventually, when I finish some remodeling in the basement I will be moving the station and the tower down there and the web cam PC will go in the dining room or living room. I will handle everything through Remote Desktop so I won't need all the LCD's. Still working on the Kodak wireless photoframe so I can have wall display of conditions. The ISS will be going higher this weekend and then after I paint trim on the house, the ISS will go up on one of the eaves.
