One time I got caught in a thunderstorm on my way into the office and I was able to dry my shoes and socks by putting them in front of these very same computers. I should have gotten a pic of that. Yeah, they are loud all right. And very hot. I had them in my office for several weeks at one point while they were being transferred from one server room to another. I had a fan blowing on them most of the time so there was that noise on top of the noise from the machines themselves. When they get sent to the surplus store, I'll post a link here just for giggles. PS: We lost the keys so the doors are held shut with velcro.
