Will answer questions later when I'm in a more tip top condition (as it were) but just to say now have system set up at home, with two minor problems... firstly I didn't think of power setup: I need 9 sockets to run my system, so tomorrow will be buying a couple of extension leads. Secondly, I insisted on delivering it, because I enjoy driving vans on occasion. Unfortunately, I enjoy driving vans because of teh reckless way you can drive them, and I have a bad feeling some screens will be smashed after a deceleration from 45-0 I estimate at 0.8g... not quite at the threshold of grip but bloody close to it... and they were poorly packaged... one of them is certainly quite damaged on the exterior...
(Oh and I dropped some outside the office too)
