The image on my current rig is very small. About 5 GB for just the windows image and apps themselves (basic apps and motherboard drivers, and all lof the operating system tweaks. Cable modem tweaks, registry edits - everything. It restores it to like new. Right now I use Acronis and like it better than Norton. As a matter of fact, im going to restore a fresh image tonight as well as build an M7NCG 400 system with a barton for my In Laws

Should take about 3 hours to build and tuck wires very neat and I'll Prime 95 it overnight. There are other ways of doing it without an image. You can boot to your windows CD and pick reinstall the operating system, you would get a fresh installl, but you would have to reinstall most apps and get SP1 and DX9 again ... etc... alot of people do it that way. Or use system restore to a known good point.
