posde read up im taking Andrews advice which does pro installs .... (2) 6e for hdmi and (1)5e or 6e for usb hub to hide behind tv... this allows equipment to be installed via distanced from plasma ..... if not there will be way more wires....
im gonna post pictures for you all of the media closet and and all Plasma locations so u can get a visual... and as many have said having extra cables is better than not enough with that said pics to come..
I would really suggest just thinking for a moment about what your embarking on here...LinuxMCE is a big complex system that needs a lot of time to understand and get to grips with. You aspirations for your new home are all achievable and technically feasible and i am sure given time you, like many others here in the forum, will acquire all the skills and knowledge needed to put the system together for yourself. But if I were you I would think very carefully about getting Tschak909 involved to at least help you plan out your system and so you dont make mistakes and bad choices early on.
The worst thing you can do is just to go out and buy a pile of hardware and then try to make it do what you want... you'll get frustrated and disenchanted with the whole process. I would suggest that spending a little of your budget now with Tschak909 (who really know this system inside out... and is reasonably close to you unlike me who is 4000 miles away ;-) ) is really a very sound investment in getting your install right and at the same time learning about the system from a supremely expert person.
Alternatively just build a small understandable system now and learn by experimenting with that first (you can still install all the cabling and other 'infrastructure' into your new home now so your ready to do the full system later). You could still get Tschak909 involved to help you learn whats needed on this system too... that would make sense.
My suggestions for how you should architect your system are 100% sound... we install systems in this way all the time. However I am not 'close by' and if you hit problems I cant be of very much help...Tschak909 can. So again my advice is that if you want to go ahead and dive strait in and integrate LinuxMCE into your new home then I would get Tschak909 involved to make sure you get it right.
Of course I am happy to continue to help you via the forum (I am here everyday anyway ;-) ).
All the best
