Just an update to this thread I don't have any OS disks to install, but if you ever want to play around with an old OS like Linux or Ubuntu, but you don't want to have a system dedicated just to that OS VME's are a great way to check out how they run. Linux and Ubuntu OS discs are pretty cheap to so I'll probably play around with those operating systems first. I do want to build a windows 10 VM to play around with viruses and malware at some point though.
