What I would recommend: go out and buy a "small" new h/d, say, 150GB or
250GB. Also get an adapter for it (let me note that I actually bought, a
year or two ago, a hot-swap drive bay that fits in a std. tower case...).
Then partition that (we've been using 1G for /boot for years), mount it on
/mnt, mount newdrive/boot /mnt/newdrive/boot, and rsync -HPavx /.
/mnt/newdrive, and rsync -HPavx /boot /mnt/newdrive/boot
Then grub-install /dev/newdrive, and swap drives.
