:: Does this work reliably when switching the whole system :: (motherboard, processor, disk controller, ...)? Define reliably! :) For most Workstations this works fine, Servers need a bit of planning and home PC's can be a nightmare. :: Won't the system load the wrong :: drivers before it can recognize that it needs other drivers and :: starts to install them? The cloning software I'm most familiar with has a utility that allows drivers to be preloaded. W7 and to some extent Vista have a better database of drivers inbuilt and at the very least will boot and just require the new MB CD to be inserted. W7 beta/RC1 loaded onto my 4 year old system with no problem, only the sound card wasn't recognised.
