Lol, I am the same way. Although on older computers, I wouldn't use ubuntu. I would use puppy linux. I inherited a windows 7 professional desktop from my mom's work (at that time she owned her own), and the first thing I did was open it up. I then when through an older computer for some more DDR3 ram. The end result: A Power computer running windows 10 pro. Unfortunately, It didn't have wifi built in. I either have to plug it in via ethernet, or use a wifi adapter that is VERY slow. I am dual booting it with a distro of linux. I'm either using linux Mint, Ubuntu, Debian, or kali. In all honesty if I went down the kali path, I would also install one of the major ones too.
