Color can make a difference in walls, ceilings, floors and counter tops. It alters mood, sometimes for the better and sometimes not. I am not sure how or why it would make a difference on a computer case in a vault where it is only seen once a week at best and more likely, once a month or whenever a problem is noted. Call me crazy (you wouldn't be the first), but I do not believe that it matters.

Bike rides are fun: 7.49 miles in 30 minutes, 34 seconds.
