I love my home office. It's a great blend of a "professional home" office.
I am on the road right now and don't have access to all my pictures. This is my main work station. The desk is professional grade made by
Hon, and I have another identical set up next to it plus the matching Hon credenza behind me. My computer is a Alienware Aurora r4 with three monitors.
I am not sure why are are talking about heating and cooling requirements, but... I never ever have to heat this room, and in the summers I have central air so I am good.
I also have a second office set up in my bedroom - just a simple desk and a Alienware M18x laptop. I call this the "battle bridge" and I work here late at night sometimes.
