50 DIY server equipment

In the past I’ve written about some of our home technology items that we’ve installed since moving into the house in 2003. From thousands of feet of structured wiring to whole house audio, I love pimping our pad with as much technology as possible without making the house look like a crazy bling’d out MTV Cribs house. Overblown home tech installation is a hobby that I really enjoy and something very unique and unexpected in a small house.

Several years ago, when I could see our home tech plans coming together (and I love it when a plan comes together), I could see the growing need for a nerve center for the home. All of the structured wiring had already been laid out to make home runs to the basement, but they all terminated to a disorganized mess that was hanging on the wall.
