Simply buy a 3.5" external enclosure, and if the drive is indeed intact, you'll have no problem accessing it.
Do note however, that you won't be able to use installed programs, only access data files. So I'd suggest just moving those to the laptop and then formatting the external drive for use as storage space.
My dell dimension 4500s desktop was damaged by lightning, however the new 160 GB hard drive survived. I am replacing the computer with a laptop, but would still like to access the data stored on the drive. It is partitioned into two drives: C, which has Windows XP Pro SP2 and D, which has all my programs and personal files installed on it. Is is possible to make it an external drive without losing any of my data? Unfortunately, while there are other desktops in the house, none of them have big enough hard drives to store all of my data on. Before you chide me, the computer was plugged in through a surge protector and was off at the time of the strike. I would appreciate any feedback, thanks.
