I am thinking about doing this as my house is being built (currently only the foundation is set now).
Anyway, I was thinking of installing Cat 5e, Coax, and a few 14-gauge stereo lines for surround sound in the new house (with the builders permission of course)
He has allotted us only a few lines for cable and phone only but nothing for ethernet and each extra box for cable and phone is $40 each

Have any of you guys done this before? Any tips or advice on equipment/sellers? there are a couple of different ideas I was thinking of doing, but would also like some other ideas in case you all have done something cool I havent thought of
I am pretty sure I want to put the central point in a little niche where the washer and dryer will be (it's the only place I can find where I can put a shelf, etc out of sight)
I was also thinking of using a patch panel with a router and ups on a shelf. I dont know yet how I am going to do the coax. The wallplates are another thing
I will save alot of $$$$ by doing this, but am not really sure if its worth it. Any input you guys can give would be greatly appreciated
