PS: On a Mac, you can usually take a hard drive out of one machine and put it in another and it will "just work". How much tweaking to get the same result on linux/ubuntu?
network cards and significantly different disk devices (ie pata, sata, some strange raid) are usually the only hurdle, but also gfx card if you are using X.
network cards are usually just a matter of changing the mac address, or some other minor changes
gfx is usually just a matter of reconfiguring X, if you are using anything inside the nvidia range, you can change cards without much fuss.
hard disk games with /dev/hda /dev/sda /dev/cciss /dev/someotherraidthing are usually just a matter of editing the fstab and rebooting. in this instance setting init=/bin/bash in grub/lilo is your friend.
