Yep, I've been in touch with Britain and much of the steps I've been following have been based on his recommendations and along with other friends who have done similar builds.
The Autodesk Autocad 2012 I'm using is an educational license from when my kids took a course for a project over the fall for a jr high project. Good for 3 years iirc and updates that come along. Definitely could not afford it otherwise. I'm using it on my Hackintosh with a 3.33ghz quad core and 16gigs of ram and touch pad so it supports gestures for zooming in, rotating etc, really slick!
