You might also want to consider a recessed outlet kit (see link below). These kits take any decora outlet (110v or low-voltage such as coax cables) and make them recessed. They also have a cover you can use that you can drill a hole through for your cable and make a very clean look. We used them in our home theater and they look great. Here is a link that might be useful: Recessed clock outlet kit

ctnewbie - I've seen some kitchen desks that have a hinged false back in the knee hole area that is 3-4" out from the wall...all the cords go down a grommet from the desktop to the space between where they're all plugged in....wish I had a picture, but I hope you can understand what I mean. bestyears - I love how you have all the chargers labeled! I'm always trying to figure out which charger goes to which phone or music player or game device. I even have a labeler...why didn't I think of that?

W = White X&Y = Black & Red; does not matter which is which

Brad covered this well. I had a single duplex outlet installed above all of my fireplaces, as well as 1x coax and 1x cat6 in the another duplex box. True I don't want a TV in every single room over every fireplace, but I wanted the option to. A picture or a mirror over the fireplace covers these. Something Brad posted (and most people miss) is the studs which a TV mount bolts in to. Most TV mounts are 16" wide, but you want the mount centered. If you have a telescoping arm on the mount, they almost never sit centered and are offset. This is why what Brad did is great, as it lets you put the mount wherever it needs to go without modifying anything. True they make very good toggle bolts that just grip the sheetrock, buy why not use wood studs if you can? Also, take good photos of every single one so you know what you working with once everything is done I also ran extra conduit (smurf tube, flexible pvc, etc) from each of these to my unfinished basement. IMO all of my "over the fireplace TV's" will never have any boxes connected to them, but ya never know. You can also transfer HDMI signal over cat6 if you really need to (say for security cameras, not a 4k movie...) so some people run 2x cat6 cables everywhere just to future proof. I didn't Plan an "IT rack" space somewhere in your house. Most use an unfinished basement room, the cabinets can be locked etc so that part is up to you. Yes everything is wifi today, but hardwired is always better and more reliable. Depending on the size of your house, most will do a WAP (wireless access point) system instead of a single bulky wifi router that sits on your basement IT rack or another bad spot. Planning a WAP puts your wifi router in the best possible location in your house, or you could do 2 or 3 WAPs to make sure there's no dead zones etc. Anyway, these need cat6 ran (from your rack) to their location (and sometimes 110v outlet so plan hardware now). Same with security cameras. If you want them or to wire for them, that all needs to feed to your IT box Put your IT box on its own circuit. It might not pull a ton of power on it's own, but you don't want a vacuum cleaner tripping a breaker on accident and killing your data signal for the entire house.
