Rebuilding the floor of my Server Room Part 1

I am starting my Server Room floor replacement. It will take some time and I will be showing live action and discussing what is going. I hope you you fallow along as I attempt to replace a floor myself. I don't work with wood all that much because it was never something I was interested in. I am doing it because I did replace my basement stairs a while ago and they turned out alright. Plus I just don't have the cash to pay someone to do it.
