Do you actually want Windows or just the data from that machine? If the latter, then assuming the HDD is formatted in NTFS, you'll want to get
Paragon NTFS and then connect the HDD to your Mac using a SATA->USB adapter and get access to all of your files/data.
If your intention is to run Windows, then depending on your performance needs, you can install Windows through Parallels/VMWare Fusion/Virtualbox (faster to get going, sacrificing some performance to not dual-boot) or Boot Camp (Native Windows experience and performance, but need to dual-boot between Windows and OS X) and then plug your HDD into the machine to get your data again.
You will likely have to re-install any applications you used previously through their installers.
As the others have stated, you are not going to be able to just re-use the HDD in its current shape.
