Have old HDD from macbook with 10.6.8 installed, how can I clone this to virtual box (using PC)

I hope this is possible.

Old mac stopped booting up, but the hdd is fine. I have it in an external case and am reading it on my pc through hfsexplorer. According to the systemversion file it is running 10.6.8

I would like to restore the old computer to a virtual machine and am wondering how I would go about doing that on a PC?
