it works great as a linux workstation, but its just so hot. My whole room is the warmest room in the house. I actually have to run a window air conditioner in the room to make it comfortable (I work from home, so use the office all day). I imagine its probably one of the largest power consumers (including the cost to cool with the window ac) in the house.
I look forward to tax season, I am going to replace it with a new AMD 3700x based system next year.
