how do i get files off an old laptop (HiTech xp) hard drive?

i had a laptop a long time ago that had wine spilled on it and it turned itself off (obviously), i recently was told i could get the hard drive out of it and hook it up to my PC (which was also on XP) and then retrieve the files.

I opened up the PC but the connecting wires didn't fit this hard drive.

I am not a technofobe but neither am I qualified in anything IT related. I would be grateful if anyone could give me a step by step, easy to follow (for those who know nothing about computers) guide on how to get the files.

Do I need a peice of hardware to connect the old motherboard to a new laptop? Can I do it from that to my new Windows 7 laptop?

In case it helps, here's the info off the hard drive:

Hitachi

Model: HTS424040M9AT00

4200RPM

SV 1.0A DC 40GB ATA/IDE

I hope someone will be able to help and point me in the right direction. Thank you very much in advance.
