CAT 7 Install or run away
Discussion
Guys I am in the process of buying a new build and would like to wire it Network as well as a couple of extra runs for HDMI over CATx.
A guy I work with has a load of CAT 7 Cabling spare from a DC project he did a while back and is happy for me to have. Is there any reason to avoid using this given the house shell is bare wall at the moment ? Or am I making a future headache.
I am assuming I will need a decent cable installer rather than trusting the site spark.
Plan B would be for the spark to run the cable at the same time as the electrical and leave it behind plaster fo rme to "knock out" later to terminate. Any reason this would be a bad idea ?

Perfectly good idea. If you terminate to a patch panel in a hub area and keystone jacks with faceplates in the room then termination is not too difficult.
If your sparkie is up to it then great otherwise just ask him to leave the wires trailing and get practising yourself. With a decent tester you can easily work out if it has been done correctly or not.

The snag with that is you can't test it until it's too late to do anything about it. I'm sure people who work with this stuff every day don't give it a second thought, but you do have to be a little bit careful not to be too rough handling catx cable and not make bends too tight.You shouldn't really run the data cable parallel with the power cables, it's ok to cross over it occasionally though.
As for getting a sparky to install it make sure he know's what he's doing first. I once worked on a job where the client had tried to save money so got his BT Engineer "mate" to install the data on the cheap. When we came to install the IT equipment none of the sockets worked as he'd not followed any wiring scheme, just done them all the same. We had to reterminate every connection.

Pin assignment is unlikely to be the problem, and even if it was, relatively easy to fix. Your bigger problem is likely to be the HDMI balum run as according to most specs, they don't like intermediate terminations. Having said that I run Octavia's HDMI matrix over dual cat with lots of hops in between and it seems pretty much fine. The run is approximately HDMI -> Matrix -> 3m Cat6A patch -> wall -> 20m Cat6A solid -> panel -> 1m Cat6A patch -> 25m Cat6A solid -> wall -> 3m Cat6A patch -> balum -> HDMI.
P.S. The lessons I learnt from the project, one hire a Fluke DTX-1800 cable tester to make sure the cables and termination are good, two learn to terminate yourself (the tool-less jacks I found were dead easy, though my installers had difficulty (though really you should know not to leave tails around metal jacks without being told)).
